RE: [cobalt-security] pmfirewall , IPCHAINS, CDONTS and mail forwarding

["Sean Ward" <planxty@xxxxxxxx>]

Thanks!  Now if I can just figure out why I can't add the nameservers to
the pmfirewall.conf without the box dropping off the net... 

DO I need a similar rule for port 53? 

Thanks, 

Sean

You have port 25 being accepted coming in not going out.... Add
$IPCHAINS -A output -p tcp -s $OUTERNET -d $REMOTENET 25 -j ACCEPT
