I have taken out all the stuff about the tun0 interface (that isn't
there) from the config. I'm left with a pretty normal config
alg icmp
procedure log
group default {
pass stateful out final all
block all apply "log"
block in final from <blocklist> apply "log"
a bunch of individual pass rules
after starting, even outbound ping fails, and I see in messages:
Jul 8 09:29:21 n11 dhcpcd[826]: ps_root_recvmsg: Network is unreachable
I then did
telnet 1.2.3.4 30
where 1.2.3.4 is another host. tcpdumping there showed no SYN arriving.
after
/etc/rc.d/npf onestop
doing telnet again showed the packet arriving at the other host.
