When you have edited the local.arp configuration, to support a manual NAT, what must be
done to ensure proxy arps for both manual and automatic NAT rules function?
A.
Create and run a script to forward changes to the local.arp tables of your gateway
B.
In Global Properties > NAT tree select Translate on client side check box
C.
Run the command fw ctl ARP –a on the gateway
D.
In Global Properties > NAT tree select Merge manual proxy ARP configuration check box
The command fw ctl arp displays the ARP proxy table on Check Point Security Gateways that run on Windows. On Unix, use the arp -a command.
Merge manual proxy ARP configuration merges the automatic and manual ARP configurations. Manual proxy ARP configuration is required for manual Static NAT rules. If a manual ARP configuration is defined in the local.arp file and Automatic ARP configuration is enabled, both definitions are maintained. If there is a conflict between the definitions (the same NAT IP address appears in both), then the manual configuration is used. If this options is not enabled and Automatic ARP configuration is enabled, the Security Gateway ignores the entries in the local.arp file.
