What settings and where do I place (order) loopback rules for firewall? Looked at standard loopback rule: UDP/TCP Out (local)Any Port (remote) 127.0.0.1/255.0.0.0 Any Port. Must work with other security software. Loopback rule? UDP/TCP ( both directions ) local (any port) remote 127.0.0.1 (any port) any application Set to block.
The standard loopback rule comes from BlitzenZeus default replacement ruleset for Kerio 2 firewall. Rules need to be placed in right order to be effective. (UDP/TCP Out (local)Any Port (remote) 127.0.0.1/255.0.0.0 Any Port) When I ping localhost all packets are sent and received with 0% loss. UDP/TCP ( both directions ) local (any port) remote 127.0.0.1 (any port) any application Set to Deny.
