I have recently added a 2nd Internet source (for redundancy) and I want = to know how to make FreeBSD choose a primary outbound internet source, = and chose the other if the primary is down? Am I correct to assume that FreeBSD will automatically return incoming = requests back through the interface that it arrived on? e.g. Internet request coming in on interface-A will return via interface-A and likewise for interface-B Thanks Tom
