static IP assignment through a bridge ...

Bridges are layer-2 devices, so if it auto-learns the MAC addresses on each
connected segment, as most of them do, this should work just fine.

If I understand your question correctly, if you create a static assignment
in your DHCP config, your router, which has a fixed MAC address on its WAN
interface, should get the same IP address every time.

Subject: static IP assignment through a bridge ...


I'm wondering if the following is possible

dhcp server  -> ethernet -> Bridge device -> ethernet -> router (dhcp  

Is it possible to statically assign an IP address, to the router,  
based on the MAC address of the Bridge? ie, no matter what device is  
put inside the bridge, an IP will be given to it, same one each time?
