Hi!
Wonder if anyone is able to provide us with some assistance.
We have installed FW1 NG Feature Pack 2 on Red Hat Linux 7.1 as provided by Checkpoint. We are experiencing problems getting Hide Nat working. We want our internal network to have their addresses NAT'd before going out on the internet.
Using the Automatic NAT Configuration for the internal network object will work fine if we select the NAT address as being the IP address of the external NIC on the firewall.
However, this is not best practice so we want to use another valid internet address to hide behind, but when this is set all external traffic fails-although the firewall log file shows the outgoing packet as accepted ok.
We have a suspicion that this is to do with either ARP tables, Routing tables or both and have added manual arp entries to map the hide nat address to the mac address of the external adapter but still nothing!
Any ideas anyone??
