Linux equivalent of Windows ICS?

General Computing *nix and other operating systems

Can anyone point me at a suitable numpty-level guide for such a function (if it exists) - my googling skills are letting me down ATM :frowning:

Shouldn’t you be working?

Must be be, isn’t that what the LTSP and servers use?

Linux has always been good at this , notably distros like smoothwall that give a sof’tware firewall - normally run on an old machine - even an old 486 will do- here’s something to start you off linky

there are a couple of reasonable firewall configuration gui’s as well, firehol being one. Basically they all mess with iptables creating very specific rulesets of what traffic is allowed to do what :slight_smile:

Thanks all.

Just to offer a bit more info: I’m not interested in a dedicated firewall a la Smoothwall/IP Cop/Devil Linux type distros - I have 2 dedicated crunchers on a dial-up line which historically ran 2k then XP with ICS. I recently replaced the client with a Linux box which was OK, but when it came to replacing the ICS ‘server’ everything fell over in a heap after the fresh build went on.

I think I may be suffering from the same issue Mortlake had with McAfee locking out non-McAfee clients which I will investigate first but I want to look at the alternative plan if it all goes Pete Tong…

don’t quite know what you need, but if you want to look at an old iptables script I made up for firewalling between about 4 NIC’s in an old P166(ish) you can find it here

http://www.spaceboy.co.uk/general/firewall2.sh

this nat’d all outbound traffic to a single IP and allowed certain ports between certain interfaces iirc

complete overkill but there if you need to fall back on something :smiley:

If you want to make it really simple I have somewhere an ethernet to modem adaptor. would support dial on demand networking and printer sharing. Never threw it out as it once cost a fortune. Not much call for sharing a modem between 256 PC´s these days.

56k in 10mb out.

Used it for quite a while
