Hi everyone!

I have a LAN that has a Firewall to distribute packets from the Internet
over my LAN. The Firewall also masquerade the machines behind it. Now come
my problem! Has it ANY possibilities of a DNS server that is behind the
Firewall becomes public for the Internet? I do some experience about that
but no one works. Some one can help me?

My Firewall settings:

ipchains -P forward DENY
ipchains -A forward -j MASQ -s $LOCALNET -d $INTERNET -i eth0
ipmasqadm portfw -f
ipmasqadm portfw -a -P tcp -L $PUBLICIP 53 -R $LOCALIP 53
