A better suggestion would be to have 1 in / 1 out. Your ISP connection is going to the 'in', and your 'out' (LAN) goes to the hub/switch, and then all your other PCs would connect to the hub/switch instead of your proxy computer. With this scenario, you could use PMFirewall suggested by others, which uses ipchains to setup the proxying. Thanks... Dan.

Re: [expert] Proxy/router setup How-To
Yeah, I've already used FreeSCO. That's more of what I was looking for, but I was thinking that I might want to do a bit of web browsing from that machine. Also, FreeSCO only allows me to hook up 2 pc's directly. I do have a coupla hubs, but I really don't want to use them anymore. I'm trying to graduate to something better.

> Why not just use ipcahins? I have written a couple of scripts PMFirewall is a set of scripts for automatically setting up ipchains rules. It asks simple questions (what is your external interface, do you have a telnet server, do you have an FTP server) and builds the rules for you. So it *is* ipchains. :) -- Ben Reed ([EMAIL PROTECTED]) http://defiance.dyndns.org/ Fight the InterNIC! http://www.opennic.unrated.net/
Re: [expert] Proxy/router setup How-To
While the thought of buying another piece isn't too appealing to me (I have a mylar bag with about 10 NIC's in it already) it looks like I might just need to buy a switch and remove 2 NIC's. PMFirewall might be the answer. Any other suggestions?

Sorry I can't > remember the URL at the moment. George, while I love PMFirewall (it's what I use at home) you may have a little trouble with it. Last I used it, it only checks for an "external" interface, and an "internal" interface. Since it's going to be acting as a switch instead of a router (1 NIC card for each machine it's connecting to) there will be 3 internals. PMFirewall doesn't think in terms of multiple internal network interfaces. It's probably not too difficult to hack in, but you may have better luck with something else that can do what you want out of the box. If you weren't trying to do it exactly as you're doing it, I'd say use PMFirewall. Personally, I've never tried to set up a switch-style linux router, so in my case, PMFirewall rocks! :) -- Ben Reed ([EMAIL PROTECTED]) http://defiance.dyndns.org/ Fight the InterNIC! http://www.opennic.unrated.net/
RE: [expert] Proxy/router setup How-To
Why not just use ipcahins? I have written a couple of scripts for this purpose I will post them as soon as I find them again :) also if you go to freshmeat.net and do a search for ipcahins scripts http://freshmeat.net/search/?q=ipchains+script You will find what you are looking for. There is even a very nice webmin module for ipcahins that makes setting up your own rules a snap. http://www.niemueller.de/webmin/modules/ipchains/ Hope this helps :) again I will post my proxy scripts as soon as I find them. I really should keep myself more organized.

Try doing a web search on PMFirewall. I use it myself and it is great! It's also really easy to set up, and easy to customise if you know what you're doing with ports & packet filtering.

[expert] Proxy/router setup How-To
Just want to know of a good resource on setting up a proxy server/router using linux. What I want to do is have 1 machine for my proxy that also provides my internet connection to 3 other boxes. The 3 machines also need to be able to transfer data between themselves. The box I want to use is a P133Mhz machine w/32Mb, 4 NIC's (1 in/3 out), and Mandrake 7.0
