R80.10: Automatic Proxy ARP with Manual NAT rules

by Rick · May 18, 2017

When releases like R80.10 hit the spotlights there will always be new features that don’t get immediate attention.

Something that changes with R80.10 is the new ability to enable automatic creation of Proxy ARP for manual NAT rules. Sounds nice, right?

Previously, when you used manual NAT rules with pre-R80.10 Security Gateways, you needed to either add proxy ARP through CLISH or by adding it to local.arp as described in sk30197. That’s an article every engineer might have dealt with in the past.

Forget about manual adding proxy ARP with R80.10. Search for ”Automatic creation of Proxy ARP for Manual NAT rules on Security Gateway R80.10″ in Support Center or open sk114395 here. You’ll learn that you can enable this nice new feature by modifying the files $CPDIR/tmp/.CPprofile.sh and $CPDIR/tmp/.CPprofile.csh.

Has anyone tested this already? Please let me know the results.
