Wireless Bridge questions (Antbox 52 15s)

Thu Feb 10, 2022 4:19 pm

Hi all, my first post in this forum :-)

Just bought an Antbox 52 15s to use as a repeater / extender :-)
Configured the two wlan interfaces (2.4 & 5) as repeater / extender with NAT and DHCP on the wlans and all is working fine.
The network consists of a Mikrotik device managing DHCP (192.168.0.x) and its connected to a Watchguard firewall and a mix of Amplifi Aliens and Netgear devices as APs.

My question relates to when I tried configuring the two wlan interfaces (using) bridging with the already existent network (192.168.0.0, Mikrotik devices) without NAT on the Antbox.
DHCP provided IP addresses from the DHCP server (192.168.0.X) works. Obviously no NAT is used in this scenario.

Network starts behaving strange when the below config is applied.
Please help me to understand: Is this setup supported? If so please help me with the correct config.
