I have set up IPCop 1.2 (and 1.3) with port forwarding port 25 on its
red interface through to an internal IP address on a mail server.
I have enabled external access for that port.
When I try telnet IPaddress 25 from an external box I get a time out.
I can ping the IP address on the IP cop box. I can also see the NAT
session under connections; however I always get a time out. I have
tried port 50000 to port 25 and get the same.
If I put the mail server on the public IP I can talk to it.
I am going to wander off to prod the network with ethereal; however I
was hoping that someone might have some bright ideas. My ISP here is
Claranet and the IP address if you feel the desire to prod is 213.253.36.55
Kind regards
Xander
