I have two office locations that each have DSL service. I have the routers set up so that the two subnets, 10.0.1.x and 10.0.2.x, correctly keep data on each subnet and or pass across to the other subnet as needed. However, I would like to have my telephones connect across the internet link. The phones use MAC addressing, so I need to bridge the packets for the phones across the internet link. The offices are small, so bridging everything would be OK, too. I have been searching around and have found key phrases "remote bridging" "concurrent routing/bridging" and "integrated routing/bridging", but, I'm not sure I'm in the right search space.
Is what I want to do feasible? What search terms might I use. I'm willing to buy dsl routers for both ends to make this happen.
I'll admit to being a dufus using 10.x.x.x address space. I just liked the number 10 more than 192, but now that I realize most equipment expects the DHCP server in the 192.168.x.x address space I'll know better next time. I'm all static IP addresses in my setup, fwiw.
