In m0n0 you don't have to explicitly set the default gateway. There
isn't a way to "set" the default gateway on the DHCP lease, because it
will just be set to point to m0n0's interface IP address.
You would be able to move the machiense between the subnets seamlessly
by setting DHCP on those interfaces that you would like to move
between. As your machine connects to another interface, it will pick
up the new lease and use the new gateway.
