One nic card is having local LAN ipaddress and the other is taking an ipaddress from the ISP through dhcp protocol. The problem i am facing is when i use the gui utility to configure the firewall i am not able to see the second nic card(during installation i was able to see both the nic cards) which uses the dhcp for an ipaddress Can anybody help in configuring a firewall for the this setup.
