Hello,
I seem to be having some trouble bridging interfaces in FreeBSD 6.2-STABLE.
What I have are two interfaces
rl0 - 192.168.2.2
sis0 - 192.168.1.2
and a bridge I've set up following the pages in the handbook. However
frames don't seem to be routed from one interface to the other. The
internet gateway for the networks lives on 192.168.1.1 and I am able to
reach the internet from boxes on the 192.168.1.0/24 subnet but not from the
other. Tracing the route from a box on the 192.168.2.0/24 subnet the
connection times out on the freebsd box, orinoco.
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).
Good luck,
