Hello, I have a problem with my port forwarding, I'm using ipchains with smoothwall linux which is at 192.168.0.1. I am trying to run a web server from my slackware box which is at 192.168.0.142 port 80. The page works from jthe 192.168.0.142 address but over the internet it only works from my school. I cant view it here because smoothwall wont let me, and other people on the internet cant view it eather but they can see that port 80 is open. I dont know why only my school can see it.

Here is the out put from ipchains:

thanks

The reason is that 192.168.0.142 is a private IP and only the people on that network can see it.

yeah, thats why im trying to forward it from the smoothwall machine.

Internet -- Smoothwall 203.166.25.x & 192.168.0.1 -- Slackware with apache 192.168.0.142.

Sorry I'm a bit new to linux and i don't know much about ipchains. I set up through the smoothwall web admin pages the port forwarding and opend the port but it only works from my school.

Funny thing is people from class C networks dosent seem to be able to get in but class A and B can.

RFC 1918

private ip spaces aren't sent over the internet

but reserved for local area networks

try firestarter.sf.net

actually, i got this problem too...I cant forward ports to LAN computers. someone help pls!
