Hi
I have config
RB952 bridge 192.168.8.0/24 -> LHG 192.168.0.223 <---> LHG 192.168.0.222 -> Ip Camera with static 192.168.1.18

How to access cameras ip from computer with 192.168.8.10?

I can see cameras IP over tools/IP Scan, but tools/ping shows timeout

On all bridges proxy-arp turned on
routes on 952:
DAS 0.0.0.0/0 | 192.168.88.1 reachable ether1 dist 1
DAC 192.168.0.0/16 | bridge reachable
AS 192.168.1.0/24 | 192.168.0.222 reachable bridge
DAC 192.168.88.0/24 | ether1 reachable

A bridge is a OSI layer 1/2 thing, what you need is layer3 routing. You cannot bridge between subnets, you can only route between subnets. At the MAC layer perhaps your devices could communicate (e.g. ARP), however IP is a layer3 protocol. You either have to have the same subnet on both computers (with a bridge connecting the Layer2 network below) or you need to have a router that routes between the subnets.
