Hi Perry
Wow, fast answer :D
Ok, so you say I've made two errors. First of, correct the monitor IP, ok did that (and it helped).
Secondly, you say I should delete the WAN2 subnet firewall rule???
Oh, and the interface for setting up pools is NOT logical, I didn't see the connection between adding the port, and selecting a monitor IP until you mentioned my error.
As the Secondary line is down at the moment (no cable in it ;) ), I'm going to test that the primary cable works.
Thankyou for your insights.
