port forwarding problem


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:

# ipchains -L

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.

RFC 1918

private ip spaces aren't sent over the internet

but reserved for local area networks
