Exactly My cablemodem can be moved to another machine by reseting it. But once communication has started with that MAC address it will not listen. Implementing VRRP wont do what I want because it still see the MAC address of the primary machines nic not the vrrp mac address. But Im trying to put in place a little redundancy and the only way I can come up with is by monitoring on a seperate ethernet crossover between machines and when it stops responding to traffic over that link then I would assume the other machines MAC address. Similar to VRRP with the VRRP mac address being shared between multiple machines but only one machine using it at a time as the gateway.
