Howto configure 2nd LAN-Port for Wifi-Zone

Click on the interface and create a connection type using the drop down and select WIFI, then assign an IP address rang to it. You probably should create a DHCP server for it as well to ensure that the AP is on the correct network otherwise it will pick up the previous address.

OK, but i need to access my local network from this Wifi? Ho do i achieve it?

You create a firewalll rule source wifi, any, destination LAN, any, allow, log.

You will need to patient with the AP, might take time to register with a new IP, just a warning.

Because it is a temporary setup do not worry about the HA pair.

By setting up this setup i managed to solve the inital problem. I didn´t had an Network Firewall Policy from WiFi -> LAN which suppressed all traffic vom WiFi-Clients. Duh,
