26.1.2 - Destination NAT - Can't set target port to well-known port

[duckworld]

I have some destination NAT (port forward) rules configured on my firewall for inbound HTTP and HTTPS. In the destination NAT "translation" section, I am unable to set the "Redirect Target Port" section to any of the well known ports added in 26.1.2. When I try to save my changes, I get an error saying `Please specify a valid port number or alias`. Setting the port to a manually-created alias works fine, as does specifying the port manually.

If it's relevant, I recently installed a clean copy of 26.1.0 onto a new firewall and didn't reimport my config (recreated manually).

In this case they are shown but cant be used because the underlying model does not allow them.

Right now they are shown all the time even if they cannot be used, and right now the only edge case is in destination NAT.
