Hi there,,
is there any way that i can forward internet from my computer to other pcs on the local network..
Detail is that i am behind a firewall and its ip which i use to run internet is..
192.168.0.1:8080 so i want to forward internet coming from this ip to other pcs on the lan which cannot access the internet...i want to act as a relayer..

Thanks...

This sounds like something that network address translation (NAT) could do.

There is an inexpensive commercial product at http://www.nat32.com I know people that use this, but haven't tried it myself.

Or just google for network address translation.

What is wrong with JoS. Half the time, when I post a URL it gets a non-printing trailing character that messes up the link.

Anyhow, the domain name is www.nat32.com. Just put http:// in front of it.

If you are running windows you can enable internet connection sharing. This will make your PC (192.168.0.1) the gateway to the internet. Then the other PC's on your network will automatically detect the proxy when you start your browser and they will be assigned IP's automatically from that address range (192.168.0.X).

If you are running linux then you have to IP masquerading to accomplish the same thing and you will have to configure and use the IPCHAINS utility.

Isn't this just Internet Connection Sharing or IP Masquerading (same thing)? But maybe I don't now what I'm talking about

Dear Mr. Reaver,

Kindly get back to work and quit scewing around on the Internet.

Well, if your firewall's IP is 192.168.0.1 you are probably already using NAT. The port 8080 make me think you are using a proxy server running on the firewall to get access to the internet. If you can't point the other LAN users to that IP and that proxy server, and don't have the control over the proxy server to allow them to use it, then maybe the powers that be don't want everyone on your LAN to access the internet and, as "Your Boss" says, you should keep your hands off and get back to work ;)
