by Hi all,
i really need your help with this one guys. I have put down a few other
posts but to no avail.
This is as far as i have gotten. Im using Linux as my router, it hosts web /
mail behind the router (internal network using 192.168.*.*). I am using
ipmasqadm portfw to forward the ports from the live interface to the private
machine. But it is not working.
I know that is i dial the linux box up with a modem and adjust the
forwarding rules to suit the new ip it all works.
I have used iptraf to find out whats going on and i can see the following:
202.76.128.30:1040 =
3 180 S--- eth1 x
203.134.168.14:pop-3 =
0 0 ---- eth1 x
202.76.128.30:1040 =
3 180 S--- eth0 x
192.168.5.10:pop-3 =
0 0 ---- eth0 x
As you can see, the originating IP comes in on and is connected to port 110
(pop3) it is then redirected to the internal address on the same port. From
this i would assume that the port forwarding is working. However the client
machine making the request cant connect. As yes the mail server is running
on that machine as i can telnet to it from the linux box doing the
forwarding
Trying 192.168.5.10...
Connected to 192.168.5.10.
Escape character is '^]'.
+OK Microsoft Exchange POP3 server version 5.5.2650.23 ready
Please if you can help with this problem it would be fantastic. I really am
at a loss
Dave
