"Source and destination are identical" Error


Brand new install of IPFire, latest version (IPFire 2.27 - Core Update 167).

I have gone into FirewallFirewall Options and changed Default firewall behaviour to Blocked as I (mostly) do not want the networks touching each other. The traffic that should go between internal networks will be done with firewall rules but that is a different topic.

To this end I am trying to setup the following:

Notice the “Source and destination are identical” message at the top.

It looks right to me but is still throwing that error. What am I doing wrong here?


thanks for updating swiftly. :slight_smile:

I guess you are trying to create a firewall rule that permits network communication from GREEN to RED. In this case, you will have to pick them from the “standard networks” list, not the “firewall” one.

Thanks, and best regards,

Nevermind. I figured it out.

I was confusing Firewall with Standard networks. My bad.

Thank you.
