DirectPlay, Linux Gateway, Firewall, oh my
I am currently using a linux slackware box as a gateway to share my adsl internet connection with the other computers in my house. I currently have the following in my rc.local
ipchains -P forward DENY
ipchains -A forward -s 192.168.1.0/255.255.255.0 -j MASQ
This has mostly been working well except for a few problems. The main one is for directplay based games such as jdoom and total annihilation (probally the more main stream ones also), I cannot connect to any other servers, I might possibly be able to start my own server on the linux box (under wine), however this is quite anoying and not to many games will run like that.
Also i hear that ip tables is better, what would the equivilent of the one above be in iptables. Also what about security issues, what should i have setup. I am currently running a webserver and a ssh server.
