Proxy ARP Necessary?
We recently updated our FortiOS from 6.2.3 to 7.0.1.
6.2.3: Proxy-ARP was "disabled", but SSL-VPN worked. VPN clients and servers could connect to each other.
7.0.1: Proxy-ARP needs to be "enabled". Otherwise, the SSL-VPN connection doesn't work.
7.0.1: Proxy-ARP "enabled" & NAT "enabled" = Ping OK.
7.0.1: Proxy-ARP "enabled" & NAT "disabled" = Ping doesn't work.
Does anyone know if there are any system changes for Proxy-ARP between 6.2.3 and 7.0.1?
I'd like to know what are the correct behavior and settings, and why these changes appear between 6.2.3 and 7.0.1.
Thank you very much!!
