Hooray!
VPN now works reliably first or last in the VPN+Psiphon+ProxyBridge
or Psiphon+ProxyBridge+VPN encryption chain of events on Windows.
I finally fixed a huge problem in that I could never (until now) get VPN to
work *last* in the chain (i.e., psiphon + proxybridge + VPN) even as VPN
worked fine *first* in the chain (i.e., VPN + psiphon + proxybridge).
MULTIPLE problems needed to be identified:
1. Windows TAP adapter race condition ("Waiting for TUN/TAP interface to come up")
2. Psiphon SOCKS5 proxy lacks UDP ASSOCIATE
3. TAP adapter DHCP failures -> APIPA fallback
4. VPNGate server variability (static IP vs DHCP push)
Now VPN works fine whether it's first or last in they encryption chain.
MULTIPLE problems needed to be identified, but these were the main ones:
1. Windows is too slow so we get "Waiting for TUN/TAP interface to come up"
2. The Psiphon SOCKS5 proxy supports TCP ASSOCIATE but not UDP ASSOCIATE
What took a while to identify was WHY both UDP & TCP OpenVPN configs failed
(where the VPN error for TCP was DIFFERENT than the error for UDP configs).
TCP: "Waiting for TUN/TAP interface to come up"
UDP: AIPA fallback "Initialization Sequence Completed With Errors"
What first needed to be modified in order for both TCP & UDP configs to
work (whether or not VPN was first or last in the encryption chain) was
each OpenVPN config file needed to tell OpenVPN.exe to employ adaptive
commands to set up the TAP interface, and to wait longer before route
injection occurs.
# Adaptively choose how Windows OpenVPN configures the TAP adapter
ip-win32 adaptive
# Give Windows 10 seconds longer before route injection begins
route-delay 10
In addition to that TAP adapter setup race with route injection, there is
no way around the fact that Psiphon's SOCKS5 proxy doesn't support UDP.
So the Psiphon rules.txt file needed to be modified extensively.
The rules.txt file had to be modified so that OpenVPN traffic
was handled correctly depending on protocol type. Before, both
TCP and UDP configs failed when VPN was placed last in the chain.
Here are the key changes between version 1p7 & 2p0 rules.txt:
a. Explicitly route OpenVPN.exe TCP traffic through Psiphon
Rule added:
openvpn.exe:*:443:TCP -> PROXY
This ensures that TCP VPN configs are proxied through
Psiphon's SOCKS5 tunnel.
b. Explicitly allow OpenVPN.exe UDP traffic to bypass Psiphon
Rule added:
openvpn.exe:*:*:UDP -> DIRECT
Because Psiphon's SOCKS5 proxy does not support UDP ASSOCIATE,
UDP VPN configs must go direct to the server.
c. Allow TAP/DHCP/DNS setup traffic to go DIRECT
Rules added:
svchost.exe:*:53:UDP -> DIRECT
svchost.exe:*:67,68:UDP -> DIRECT
system:*:*:UDP -> DIRECT
These ensure that Windows can perform DNS lookups and DHCP
lease negotiation for the TAP adapter without being blocked
or forced through Psiphon.
d. Block unwanted UDP traffic from browsers and apps
Rules added such as:
chrome.exe:*:443:UDP -> BLOCK
firefox.exe:*:443:UDP -> BLOCK
brave.exe:*:443:UDP -> BLOCK
This prevents browsers from leaking QUIC/UDP traffic outside
the encrypted chain.
e. Maintain TCP direct access for system processes
Rules like:
svchost.exe:*:*:TCP -> DIRECT
services.exe:*:*:TCP -> DIRECT
system:*:*:TCP -> DIRECT
These allow Windows core services to function normally while
keeping user applications proxied.
Here is the current status as of version 2p0 of the rules.txt file:
1. TCP OpenVPN configs now work when VPN is last in the chain,
because their traffic is correctly proxied through Psiphon.
2. UDP OpenVPN configs now work when VPN is last in the chain,
because their traffic bypasses Psiphon and goes direct.
3. TAP adapter setup traffic (DNS, DHCP) is allowed direct, so
Windows no longer fails with APIPA addresses.
4. Browser UDP traffic (QUIC) is blocked, preventing leaks.
The critical changes in rules.txt were:
1. Split handling of OpenVPN.exe traffic: TCP -> PROXY, UDP -> DIRECT.
2. Allow svchost/system UDP traffic direct for TAP setup.
3. Block browser UDP traffic to prevent leaks.
4. Keep system TCP traffic direct for stability.
Together with the OpenVPN config additions
(ip-win32 adaptive + route-delay 10), these rules fixed the
longstanding problem which had prevented VPN from being used after
ProxyBridge. Now VPN works reliably whether it is first or last in the
encryption chain.
Here is the version 2p0 of the rules.txt file to donate to the team.
# C:\app\network\proxy\proxybridge\rules.txt v1p0 20251023
# This is version 2p0
# # # # # # # # # # # # # # # # # # # # # # # # # # # # # # # # # # # # #
# Load this into ProxyBridge using the pb.bat script.
# Syntax: --rule <process>:<hosts>:<ports>:<protocol>:<action>
# Rules are case insensitive, # indicates comments, blank lines ignored.
# v1p1 20251023
# Added useful examples of block, direct & proxy for others to benefit
# Added usable inline comments (requires pb.bat v2p6 or higher to handle)
# v1p2 20251023
# Added usability explanations of dns complexity & QUIC/HTTPS3 issues.
# Added UDP block to handle Brave using experimental protocols above.
# v1p3 20251023
# Added clarification that TCP & UDP rules are not overridden
# v1p4 20251024
# Added Tor SOCKS5 proxy server (in addition to Psiphon's)
# v1p5 20251024
# Note that Tor cannot proxy UDP, so I had to add specific rules for that.
# v1p6 20251025
# Added Chrome, Brave, Edge & FF browser rules due to phoning home.
# v1p7 20251024
# Fixed error that Psiphon doesn't support UDP ASSOCIATE
# This is to avoid proxying UDP (Psiphon doesn't support UDP ASSOCIATE)
# Cleaned up DNS section because DNS via proxy is enabled by default
# v1p8 20251130
# Added DIRECT rules for svchost.exe, route.exe, and system UDP.
# So that TAP setup traffic bypasses ProxyBridge.
# Tunnel traffic (openvpn.exe on TCP 443) still goes through Psiphon.
# This separation allowed DHCP and ARP to succeed but Windows was slow
# to set up the tunnel until I added two directives to TCP config files.
# ip-win32 adaptive
# route-delay = 10
# Remaining issue:
# Even with bypasses, Windows was slow to mark TAP up.
# OpenVPN kept looping "Waiting for TUN/TAP interface to come up"
# v1p9 20251201
# Combined both TCP/UDP cases in a single rules.txt file by
# explicitly allowing UDP traffic from OpenVPN to go DIRECT,
# while still proxying TCP 443 through Psiphon
# Now TCP tunnel traffic is proxied through Psiphon
# While UDP tunnel traffic bypasses ProxyBridge (DIRECT)
# And TAP setup traffic (DHCP, ARP, route injection) is always DIRECT so
# OpenVPN can bring the interface up in time given ProxyBridge delays.
# v2p0 20251201
# The rules bypassed ProxyBridge, but the TAP adapter still failed DHCP.
# Windows gave it a fallback 169.254.x.x address, so OpenVPN reported
# "Completed With Errors." For UDP VPNGate configs to work, they must run
# DIRECT without Psiphon, and the network must allow the TAP adapter
# to obtain a proper 10.x.x.x lease from the VPN server.

REM <https://psiphon.ca/en/download-store.html> censorship
REM ============================================================
REM ProxyBridge hooks into the Windows networking stack to
REM observe all TCP/UDP connections to decide to proxy, block,
REM or to allow the connection to go direct to the Internet.
REM ============================================================
REM ProxyBridge has two flaws which are solved with this script:
REM 1. ProxyBridge has no import/export capability for rules
REM 2. ProxyBridge has no persistent file-logging capability
REM ============================================================
REM v1p0 20251022 15L
REM Launches ProxyBridge CLI using Psiphon or Tor SOCKS5 proxy.
REM Uses the CLI to apply rules for Brave, Chromium & stunnel.
REM Brave is sending UDP/443 traffic directly bypassing the proxy.
REM We can further disable QUIC in Braveās settings (msedge also).
REM chrome://flags/#enable-quic (set to disabled)
REM Exits with control-C
REM v1p1 20251022 22L
REM Added process:hosts:ports:protocol:action format.
REM EXAMPLE: --rule stunnel.exe:*:119,563:TCP:PROXY
REM Test with curl https://icanhazip.com
REM v1p2 20251022 39L
REM Added "--dns-via-proxy" & "--verbose 3" flags.
REM DNS is actually handled directly by svchost.exe apparently.
REM v1p3 20251022 52L
REM Added a prompt for UAC since ProxyBridges requires admin.
REM v1p4 20251022 65L
REM Added automatic external IP check via curl after launch.
REM v1p5 20251022 108L
REM Added logging of all output to with timestamped files.
REM But exiting out of multiple consoles is inefficient.
REM v1p6 20251022 115L
REM Simplified: single console window, inline ProxyBridge run,
REM Added a graceful quit with Ctrl+C, with logging intact.
REM v1p7 20251022 94L
REM Further simplified: one Ctrl+C stops ProxyBridge and exits,
REM removed pause and post-run commands for clean quit.
REM Cleaned up the formatting to remove blank lines.
REM v1p8 20251022 107L
REM Added cleanup section to ensure ProxyBridge is killed.
REM v1p9 20251022 101L
REM Simplified logging: one log file per run, no tmp clutter,
REM Modified the flow so one Ctrl+C stops everything cleanly.
REM v2p0 20251022 107L
REM Corrected logging: live console + single log file,
REM one Ctrl+C exits cleanly, cleanup guaranteed.
REM v2p1 20251022 103L
REM Live streaming fixed by having PowerShell read
REM stdout/stderr in real time, mirrors to console
REM and appends to one log file.
REM v2p2 20251022 74L
REM This became a mess so I started over with version 1p3
REM Changed ProxyBridge launch to "start /wait" so one Ctrl+C
REM stops ProxyBridge cleanly without the Y/N batch prompt.
REM v2p3 20251022 92L (whew, got it working again by backtracking)
REM Added timestamped log file with live console output.
REM One console, one Ctrl+C to stop ProxyBridge.
REM v2p4 20251022
REM Added back UAC elevation block
REM v2p5 20251023
REM Moved rules to a rules.txt file for easier maintenance
REM Added a safety check to ensure rules.txt exists
REM Maintained logging and UAC elevation
REM Preserved the single-console, Ctrl+C exit behavior
REM PowerShell invocation uses %PBARGS% instead of a
REM nonexistent ProxyBridge --config flag to break lines up
REM v2p6 20251023
REM Modified so that only one control-C is needed (sans YES)
REM v2p7 20251023 146L
REM Added usability of handling inline comments in rules.txt
REM Added common examples of block/proxy/direct/port rules.
REM This is to help others come up to speed faster than I did.
REM Syntax: --rule <process>:<hosts>:<ports>:<protocol>:<action>
REM --proxy socks5://127.0.0.1:1080 # Psiphon's SOCKS5 listener
REM --proxy socks5://127.0.0.1:9150 # Tor's SOCKS5 listener
REM --rule telegram.exe:*:*:TCP:PROXY # Example of proxy
REM --rule OneDrive.exe:*:*:TCP:BLOCK # Example of block
REM --rule brave.exe:*:443:UDP:DIRECT # Example of passthru
REM --rule stunnel.exe:*:119,563:TCP:PROXY # Example of ports
REM v2p8 20251024 161L
REM Made the rules filespec a user-defined variable
REM v2p9 20251025 151L
REM Improved comments to make it easier for others to understand

' Tutorial:
' How to Load a PAC File Directly from Disk in Firefox
' (without needing a web server such as "mongoose" to serve it)
'
' Firefox is one of the few browsers that allows PAC files to be loaded
' directly from disk using a typical file:/// URL instead of a web server.
'
' 1. Firefox:Tools > Settings > Network settings > [Settings...]
' 2. In the "Connection Settings" dialog
' Select "Automatic proxy configuration URL"
' 3. Paste the path to your PAC file, e.g.,
' file:///C:/app/network/proxy/proxy.pac
' 4. Press [OK] to save
'
' This method works on Windows, Linux, and macOS.
' Just adjust the file:/// path format for your operating system.
' A. LINUX: file:///home/username/proxy/proxy.pac
' B. macOS: file:///Users/username/proxy/proxy.pac
' C. Windows: file:///C:/Users/username/proxy/proxy.pac
'
' After setting Firefox to read the PAC file as shown above, we can then test
' by visiting about:networking#dns (set "Autorefresh every 3 seconds" & then
' we can visit a site that should go through the proxy to watch what happens.
'
' We can also check our IP on a site which reports what it sees in Firefox:
' <https://ifconfig.me>
' <https://ipleak.net>
' <https://icanhazip.com>
'
' Probably better though to check using a dedicated proxy testing site which
' can detect whether we're behind a proxy & sometimes even show the type.
' <https://www.whatismyproxy.com/>
' <https://browserleaks.com/proxy>
' <https://www.lagado.com/tools/proxy-test>
'
' If we want to test outside the browser, we can use curl with one of the PAC
' testers above or we can manually specify the proxy in the curl command.
' C:\> curl --proxy socks5h://127.0.0.1:1080 https://ifconfig.me
' If we only configured the PAC file inside Firefox, then only Firefox will
' follow the specified PAC (Proxy Auto Config) rules.
'
' Not curl.
'
' Note that if we are configuring the proxy PAC file system-wide in Windows,
' we'd likely need to serve it over HTTP (e.g., with Mongoose). In that case,
' we'd set Firefox to "Use system proxy settings" instead of the filespec.
'
' But for just Firefox alone, the file:/// approach works just fine.
'
' Below is an example PAC file that I use for my specific needs, which I've
' added comments to so that anyone else can pick it up for their own re-use.

' Another way to test the proxy from within Firefox is:
' a. Go to <about:blank>
' b. Press Ctrl+Shift+K to open the web console for that page
' c. Paste this
' fetch("https://ifconfig.me/ip")
' .then(r => r.text())
' .then(ip => console.log("Your current IP is:", ip));
' d. You should now see your current external IP printed in the console.
'
' A more permissive endpoint would be:
' fetch("https://api.ipify.org?format=text")
' .then(r => r.text())
' .then(ip => console.log("Your current IP is:", ip));
'
' What I see, for example, when I test this out for you, is the following:
