Hello Im running Potato for a firewall with ipchains. I would like to increase my security and currently have all ports stealth except 25 smtp, 79 Finger, 80 http. If I make these ports stealth will this affect the ability to use the web and mail? I also tried to make netbois stealth but if still shows as closed. I used : /sbin/ipchains -A input -s 0.0.0.0/0 -d $MY_IP 139 -p tcp -j REJECT Why is this now working?? Thanks
