Yes, it definitely does. It works as advertised.

The specifications even allow multiple gateways per network interface.

However, lwIP supports one gateway per interface.

Now, what is interesting is what the behaviour is if we have two network
interfaces, and a UDP PCB (i.e. a low-level socket) which is not bound to
any local interface address. If it connects to an address outside of the two
networks, which network will it choose to go out on?

I should see the code to see what happens.

Regards,

Leon.
