reachable gateway, unreachable bridge link wireless

Hello everyone
It’s my first post in this forum. Please excuse me in advance because my English language is very bad.
I have an Hex Poe Routerbord connect via Wan to link bridge wireless Sta Ubiquiti Litebeam AC. Link is long ~ 115 ft and the Ap Litebeam AC is connect neighbor to the bording router openwrt that is the gateway.
My problem is when I’m connect with laptop (or other devices) lan side, the link is unreachable while the gateway is reachable. To be able access to the link Ubiquiti I use ssh tunnel on the mikrotik Hex Poe or Openwrt gateway.

Openwrt gateway → 192.168.255.1
Ap Litebeam → 192.168.255.2
Sta Litebeam → 192.168.255.3
Hex Poe → 192.168.255.4

p.s. Hex Poe ports are configured as bridge and I used static route to configure my Pan network.

Below, the routes on Hex Poe:

The Lan interface of the openwrt gateway that is connected to the Ap Litebeam is eth0. The others interfaces are used to the local network office’s business.

If the information posted is not enough, please tell me and I will post it to give you the opportunity to help me with more productivity

Additional information:
I’m try to disable firewall rule on routerboard but it’s same, for the access to the link bridge for the management I have to use dynamic tunnel with ssh and socks5 on the browser.
