Hello all!
I'm using ipchains to filter packets.  I have pop open from the outside
so we can check our mail from home, I do not allow telnet into the box
or ftp for that matter.  How do I open up port 22 for ssh connections?
I've tried:
$IPCHAINS -A input -i $E_IF -p tcp -s 0/0 -d 0/0 22 -j ACCEPT
and this seems not to work.  Any suggestions?
