We have two cable modems (they don’t offer bigger bandwidth, so we got x2 
) from the same ISP coming into one of our routers. One of them should be passed to another mikrotik acting as a proxy, and the other one NATs on the entry router. Would it be a problem to have dwo identical default routes pointing to 10.40.0.1 (one for proxy, one for NAT)? The modems are on sepperate interfaces.
