Hi I have a bridge setup with two subnets 192.168.0.1 and 192.168.1.1 but I cant see the PC on either ends 192.168.0.5 & 192.168.0.22 and on the other end 192.168.1.127/128.
Both ends have their own ADSL. But I need to share 2 PC on either sides. I am using SXT-G-5HnD

Thanks in advance for any help

Hello Sir,

This is probably not working because routing has not been setup on the gateway routers, the IPs on the bridges are /32s, and there is nothing routing between the 192.168.0.0 & 192.168.1.0 subnet. My suggestion to you is:

Configure the SXts so they have a transport network (the network bridging 192.168.0.0 & 192.168.1.0), configure the wireless and ethernet interfaces with correct subnets and addresses, create the correct routing entries.

Bridge1:
IP addresses:
ethernet port 192.168.0.4/24
wireless port 172.16.1.1/30
Routes
0.0.0.0 -> 192.168.0.1
192.168.1.0/24 -> 172.16.1.2


Bridge2:
IP addresses:
ethernet port 192.168.1.4/24
wireless port 172.16.1.2/30
Routes
0.0.0.0 -> 192.168.1.1
192.168.0.0/24 -> 172.16.1.1

Main Gatweay Router A (192.168.0.1)
Routes
0.0.0.0 -> to your ISP
192.168.1.0/24 -> 192.168.0.4

Main Gateway Router B (192.168.1.1)
Routes
0.0.0.0 -> to your ISP
192.168.0.0/24 -> 192.168.1.4

Many Thanks Jorbu for your help
I think I did it right?

2 things I notice:

1) there is no need to create a bridge interface on the STXs. Since the router has two addresses built into it (the 192.168.x.x & the 172.16.x.x) it treats these as connected routes. This allows the router to route traffic between the two interfaces without having to bridge them. Remove the two ports from the bridge, then remove the bridge.

2) Your default route on the SXT says 0.0.0.0/32, change it to 0.0.0.0/0.

This should complete the config on the SXTs. Were you able to modify the routing for the default gateway?
