For this I would say under no conditions. If a packet arrives from one ISP and you respond via another the machine waiting for the packet to arrive will be confused. It's waiting for a packet from the ISP it sent the first packet to. I am not sure you could get away with this under any circumstances. General rule is what ever interface a packet arrives, reverse packets should flow over the same interface. If an app is running with a persistant connection connection to your network it will want all communication to take place over the same connection. So if it starts on ISP1, it will remain on ISP1 until the connection is broken. At which time if an attempt to make another connection is made, theoretically it will take place via ISP2. Of course depending on your weights and etc. It's like asking me a question, and a guy named Bob runs over and tells you the answer. Of course us humans having intelligence may except the answer. But if you were waiting on the answer to come from me, getting one from Bob does not cut the mustard. You will still be waiting for one from me. -- Sincerely, William L.
