99% chance that the problem is your firewall is blocking it, check to see
if the ipmasq package is installed, if it is reconfigure it(i _always_
delete it it has caused me NOTHING but trouble) flush the firewall by
running ipchains -F if you got kernel 2.2.x or ipfwadm -f<type> where
<type> is type F (forward) I(insert) A(append).
if your not specifically using the ipmasq package the system will
automatically re add the firewall rules blocking aLL incoming and outoging
traffic, if you want ipmasq, id suggest you delete that $#@ package and
setup the firewall manually(ipmasq only needs 1 rule, or 2 if your
security minded). i spent many many hours trying to figure out what was
screwing my servers up till i found the ipmasq package was doing it.
