I have a RedHat Linux 7.1 system running an
iptables based firewall. The system has one LAN NIC (static
IP) and two WAN NICs (with public static IP addresses). We
have external DNS entries that point to one of the two WAN
NICs. The firewall port forwards to internal
computers running web etc. My problem is that I cannot reference
these internal systems by the registered DNS names from inside the
firewall. Everything works fine on the outside. What rules
do I need to add to my iptables config to make this work.
thanks!
