Can you please advise whether the following scenario would work:

BM 3.8 on NW6.5

ISP1 - PUBLIC1
- fixed IPs
- private network default route
- outbound web browsing
- smtp mail in/out

ISP2 - PUBLIC2
- different fixed IPs
- BM reverse proxy for GW client, GW WebAccess, NW Webaccess, iFolder, Terminal Server etc

would the reverse proxy traffic be returned to the client through PUBLIC2, or would it be returned through PUBLIC1 ie default route?

many thanks
Simon
