I triyed with a firewall "Firestarter" but no effect. I have read somme recomandations on some forums to use IpCop but from what i know it work's only with internal ip's (as 192.168.1.xx)
I have made some changes in the last time.
I have eth0 with the ip: 89.xx.209.254, dns 89.xx.208.2 / 89.xx.208.3 and gateway 89.xx.209.1 and i have added , like virtual interfaces the ip's from 86.xx.86.10 to 86.xx.106.255 on eth0 , so i can run psybnc's on them and other services.
I have putted the IP 86.xx.86.1 on eth1 and leaved the IP's from 86.xx.106.2 to 86.xx.106.9 free to forward them and connect other computers on them.
The bad thing is that i don't manage to make the forward.
If is someone who has done this before or who can help me please help me.
Thank you all,
