Tassos,

should the MTU be different than the default LAN link MTU and if so why?
should internal to the home communication also be restricted in MTU?
if the MTU is set e.g. equal to the WAN MTU, what do you do in the case of a routed home? how do you propagate the MTU inside the network?
what if there are conflicts?

unless you have good answers to these questions, I suggest we don't.

cheers,
Ole
