Title: All working but LAN addresses not ping’able from firewall
Post by: mflammia on August 31, 2020, 11:08:28 pm

Hi,

Have a working firewall, but oddly I am unable to ping any of the LAN addresses from the interfaces -> diagnostics -> ping section.

The LAN device is able to reach the internet, it’s showing in the ARP table and I have a rule in the LAN section allowing ICMP any any.

Obviously missing something obvious, so hoping someone can point me in the right direction.

Many thanks in advance.

Do you have an explicit Deny / Deny rule one for outbound?

You probably have a rule on the LAN interface blocking traffic outbound.

Then FW uses inbound as the Source Interface and Outbound for the Destination Interface with rules.  In your case the interface LAN is the outbound.
