Re: Port forwarding and NAT

In IPCop, it must be done manually. Version 1.4 had an add on that enhanced
the GUI but nothing exists for 2.1 despite numerous requests for such a
feature.

If you search this mailing list archives ("Source NAT" might be a good
search string) you should find what you need.

I solved the problem by switching to a different firewall distribution. Both
Endian and IPFire have a GUI feature that will set this up for you.

I believe the answer is yes.   I did this years ago for a voiceIP system.
You will need to do a custom IP tables thing and stick it in one of the
files that
don't get overwritten by updates.    I don't remember the specifics, but
examples may exist in the wild.   I can try to find the backups I made but
it will a couple days.

I have port forwarding working from an outside IP to an inside IP. I am told
I need to set up 1-to-1 NAT in both directions for the server. If I
understand correctly the port forwarding is for the incoming traffic.

 

We are on a Comcast connection and all traffic leaves here under 1 IP
address, XXX.XXX.XXX.241. The server above is XXX.XXX.XXX.244. Is it
possible to make traffic coming from the inside IP, 192.168.1.15, to leave
IPCop as XXX.XXX.XXX.244?
