YES, that is exactly what provides it. Julians patches with no nat, no go. Nat with no patches no go ;) It's his patches with the natting that allows for proper lookup and route back out the proper interface. > I haven't applied those yet because up until now > I didn't think they applied to my situation.

Just look into patching a kernel and booting it. Then see what you get. I would imagine the results you want if have all the rules setup properly. > > Sure that's a nasty way of load balancing.

I have seen that and came across it during my painful trial and errors as I was trying to get load balancing working. -- Sincerely, William L.
