Multiple LAN & Fail Over... unable to stop second LAN from using 5G bandwidth

[spacecase-25]

I have 2 LANs set up, one for my normal internet traffic and one for my torrent server.  My setup includes two gateways, one my primary broadband connection and one 5G connection.  I have these grouped together so that if the broadband connection goes down, the 5G modem picks up the traffic, and that works as expected.  However, no matter what rules I try, I cannot get the second LAN to not switch over to the 5G gateway.  If broadband goes down, I want the second LAN to lose connection, rather than funneling all that traffic over 5G. 

How can I do this?  I cannot seem to figure out a rule that achieves this.  I've tried rules on the torrent lan to block traffic going to the 5g net.  I've tried rules on the torrent lan to block the 5g gateway.  I've tried rules that explicitly select the broadband gateway.  None of this stops this second lan from failing over to 5G. 

Any suggestions?  I'm out of ideas as this point and have given up for the time being.

You could create 2 VLANs, one for "torrent" and one for "normal usage".
After this you could assign only the "broadband gateway" to your "torrent vLAN" in the "Firewall/Rules" rules.
