NAT problem

Hello everybody,

Just new to the forum so please be gentle.

I have 2 WAN's on Port 3 and port 6

What I wanted to do is put the guest and staff wifi to use the connection on Port 6 instead of the main connection on port 3

I made firewalling rules to suit

Then made 2 NAT rules 

This works if Ieave the outbound on Telair (ISP) Port 3 the moment I change this to Port 6 (Node1) there is no connectivity

I thought it might be because the Node1 connection is set to a backup connection in WAN manager but that had no bearing.

The Log is showing

Can somebody please assist?

any help is appreciated.
