Hello, I need to setup a linux gateway for a lan-party. Offcourse we need to use Iptables.
More details:
we have 3 ranges : 192.168.1.0/16 (Servers) , 192.168.2.0/16 (admins), 192.168.3.0/16(gamers)

Server range : 6000:7000 tcp closed
Admin range : all open
Gamers range: all closed accept 5190tcp,4000tcp

For each user we have to know the amount of datatransfer. (just need to be shown on the screen, nothing advanced)

Are there people who can help me?

Thx a lot !!!

192.168.x.x/16 ? all of them are in same network. how do u do that?

The thing you are trying to set up is called superneting, expanding a class C network to a class B.
The question how to set up a firewall+router is asked over and over again at the forum. Did you make a search before posting.
I guess the answer is out there.

ok heres the situation,

gateway/server (redhat) 192.168.0.1 & jucks.co.uk
|
windows xp machine 192.168.0.1

the server has 2 ethernet cards, eth0 and eth1, eth0 is connected to the net, via a cable modem, and eth 1 is connected to the xp machine which has the ip 192.168.0.2,

the questions, /...

first off i need someone to help me with my iptables i need to use it as a gateway so that the xp machine can access the internet.

i was also wondering if someone could help me with this, on the windows server os's you can have domain controlders, so say my server was setup as jucks.co.uk, then i could have the xp machine as sau, inside.jucks.co.uk if ya know what i mean? could anyone help?
