Steam LAN Server missing in the list due to Broadcast Address

I have several Steam Game Server hosted in the LAN.

I use RB3011UiAS-RM router in my home, using initial default configuration.
Game Server plugged into LAN Port 4
Rest of PC use LAN Port 5 until 10

Only PC at LAN Port 5 can see Game Server running in the LAN
PC on LAN Port 6 ~ 10 cannot see Game Server running in the LAN

Not only limited to Valve game’s, EA game like Red Alert 3 LAN Play also have same issue,

I read something about broadcast address unable to pass-through between switch chip via bridge
Valve game like CS:GO, Left 4 Dead 2 are using 255.255.255.255 to announce
EA game like Red Alert 3 using 192.168.88.255 to announce online LAN player

how to tweak broadcast address able to see each other via bridge?
