Looking for the correct way to add another NIC to my current Checkpoint Firewall-1 v4.1 SP4 NT4.0 SP5 system. I have reviewed http://www.phoneboy.com
looking for a solution or help and cannot find one so I'm asking here. I want to add a DMZ to my current firewall configuration, each time I add the new NIC and configure the rules and ensure that the the firewall object has all the interfaces, the firewall ceases to seem to work (i.e. forwarding of packets). What is the correct way to install the new NIC and get it to function? Should I backup the config files, install the NIC, then reinstall the firewall and finally copy back over the config information? Or is there an easier way? Anyone else tried to do this before?
