My BorderManager current have 1 private and 1 public interface linked to
ISP1 for all email, Internet etc... , I want to add extra public interface
linked to ISP2 for cheaper internet access rate, and then later on move
everything from ISP1 to ISP2. how do I config BorderManager http proxy to
divert all http traffic from public1 interface to public2 interface?

Thank you in advance.
