A layer 2 bridge connects two physical network segments to create the illusion of a single layer 2 network. In general, you have a single IP subnet sitting on top of a layer 2 network. Think of a bridge as a 2-port ethernet switch. If you want a single layer 2 network, try readdressing the 192.168.2/24 side to be on the 192.168.1/24 subnet. If you need different subnets, you'll want to configure *routing* and not bridging (See: handbook/network-routing.html).
