Zentyal 6 Firewall - External network to internal rules

[anselal]

I did a fresh install of Zentyal 6 Development and setup a bridge between my 2 network interfaces. One is configured as WAN.

The problem is that there is no option in the Packet Filtering to config traffic from the External network to the internal.
There are only the other 4 options available.

How do I set this up ?

I found the solution at https://github.com/zentyal/zentyal/pull/536/files#diff-e90d45e982d9587840703bdc97bcf44d

It seems that they have hidden it by default to prevent confusion with port-forwarding, which is not the case.
At least they could documented somewhere.
