in USG FLEX H Series

Good morning,
I have to replace an old Zywall USG100 with a USG FLEX 200H. In the old firewall I configured the WAN interface in dhcp and I have a WAN LAN bridge configured with static public IP (see attached screenshot).
How can I replicate the configuration on the new one? I saw that in the FLEX I don't have the possibility to create a bridge between the WAN port and the LAN ports and above all it lets me indicate the IP but not the gateway (see attached screenshot… ge1 and ge2 are wan interface).
Thank you

    You need to set role as external for gateway to show up which is a change to how ZLD was I think

    For interfaces to show up in bridge you need to make a interface for the given port like DMZ this interface must then only have a zone for its reference

    Good evening, it seems to me that it is already set like this by default...

    I should make a bridge between ge1 and ge3 but among the available interfaces I only see ge1 and ge2.
    Thank you

    You need to remove ports from ge3 and ge4 then make a interface with the ports you removed no IP set then that interface will show up for bridge.

    ge3 and ge4 have IP set on them and have reference rules to them

    Good evening,
    sorry but I can only answer now... I tried the configuration as suggested: I eliminated the port from the ge3 and ge4 interfaces and created a new LAN interface. I then created the bridge (question: is it correct to put wan in the zone? Or do I have to set it in another way?) as per the screenshot but I receive the following error

    Where did I go wrong?

    Thank you
    Greetings

    ...I think I solved it... The wan ge1 interface was configured as dhcp. I set it to unassigned and configured the bridge as per the previous screenshot. Everything seems to be working. The only doubt is whether the wan zone I set on the bridge is correct or not.
    Thank you
    Greetings

    Are the interfaces you need to then create bridge set to unassigned?

    Now yes... Can you tell me if the correct zone for the bridge is wan?

    Yes depending on how you use it to make rules or make your own zone
