Hello!

I recently bought the game Planetside for my PC (wow what a great game! ) I am playing it behind a Linux machine using IP Masquerading. To host a voice conference, it likes port 37000. I tried to add it, but it didn't work. Here is what I added (It only requires TCP, but I added UDP for the heck of it):

iptables -A PREROUTING -t nat -p tcp -d $extip --dport 37000 -j DNAT --to 192.168.0.2
iptables -A PREROUTING -t nat -p udp -d $extip --dport 37000 -j DNAT --to 192.168.0.2

Any ideas/suggestions are GREATLY appreciated!!!

the rules look good, but try leaving out -d $extip and see what happens. Also, for voice....i'd think it would require udp..but as you are allowing both protocols....it doesnt matter.

What i really wanna know is in what file do i put these IPTABLES rules, every body says what rules to put no one shows where.

Further more, as a newbie could you tell me how do i test that these are working, cuase right now my Linux box servers as proxy gateway and i'd like to make it serve as a masquerading router.

Thanks

the 1st question is answered in the Router thread about where to put the rules. To test the rules you will have to try to access certain things from outside of your network and see what works and what doesnt.

if something goes wrong (like you loose your network connection due to
a strict firewall setup) just remember:

iptables -F
iptables -t name -F

to clear the firewall rules. do everything in steps, add a rule...test it...if it doesnt work, start over with that rule and do it till it works. that is the best way to do it, and when u are more comfortable, you can start to do things in chunks
when you have solid understanding of what is going on.

Hey Robert... I tried your suggestion, and no go. Any other ideas??? Thanks for your time!
