I'm working on setting up a zywall USG-100 firewall. I can get everything to work but now I'm trying to get the 2 wans to work correctly.

They both work individually but I'm having trouble with the trunk setup.

We have two connections, our main has 60/10 mbit up/down and our backup has 8/1 mbit up/down. So the backup really is just a backup to keep email and the vpn just going untill the main comes back online.

Now to setup the wan trunk I have 3 protocols I can choose: - Weighted round robin - Least load first - spillover

Now I can sorta guess what they do, but not exactly. Now what protocol should I use and with what settings (weight or speed)??

I hope someone can help me, if more info is needed, just comment.

as you can see these are the only options I get

In the manual, is there a "failover" option? That's what it sounds like you want: fail over to the 8/1 connection only if the 60/10 goes down. – gravyface May 23 '11 at 13:17
Nope, sadly there isn't one, I've requested a solution to the manufacturer, Still waiting for a reply... – s4uadmin May 25 '11 at 11:34
weighted round robin will allow you to give a higher weight (like 80/20) to your faster connection. Are there any failover options within that option (in a sub-menu somewhere?). – gravyface May 25 '11 at 11:40
(updated post) As you can see these are the only options I get... What weight should I give it? just one higher or something like 10? – s4uadmin May 25 '11 at 11:46
Check the other connection as passive from the trunk. – user97408 Oct 10 '11 at 15:40
