I would propose the following:
A.) by default, add for every interface, a little advanced routing which makes
packets return from the same way they came.
This usually is only useful with incoming packets, but can still be useful if
laptops have for example 2 gateways because the wifi is still on and the cable
is too. That would mean that from both interfaces it'd be possible to use ssh
or vnc or whatever.
this is possible with incoming packets, but, how do you select the
source of a new one?
B.) if we have multiple gateways (like in that case), have them use both
balancedly. ie: start a small daemon which checks which of the gateways is up
or down; and change the default gateway accordingly, or even both in some kind
of balanced mode. (with advanced routing.)
This could go wrong in so many ways i would not even try:
i.e. how do you determine if a gateway is up? dont tell me icmp, many
firewall refuse it, and vrrp standard says the backup gateway should not
answer icmp echo.
