Hello I am trying to run ipchains firewall on my computer connected to corporate nettwork. I created a set of rules that let web and mail and ssh traffic in and out, and it works just fine. But i got a problem with NFS and samba traffic. I did not manage to get it running until i placed "-A input -s 0/0 -d 0/0 -i eth0 -j ACCEPT" in the ipchains.conf file. But, as far as i understand this opens for all traffic to all ports over eth0 ( which is the only network interface in my computer), which is not 100% secure.. or am i wrong here? I have tried to remove the above line and add "-A input -s 0/0 139 -d 0/0 -i eth0 -p tcp -y -j ACCEPT" to let samba traffic in, but nothing happened ( it startet to deny all kinds of traffic)
I have tried to search around for hints how to set up ipchains, but all examples i find describe how to make a conf file for a firewall with a whole nettwork behind, but not for a stand alone computer. I feel kind of lost here... and IPchains-howto on linuxdoc didnt help a lot. Some can help a little? May be someone knows of some examples i can look at? Thanks in advance -- Victor
