Three or more wan to vpn site-to-site - sonicwall

Hi Experts,
I have the following scenario:

Site 1:
WAN 1: 177.10.10.2
WAN 2: 182.11.11.2
WAN 3: 201.14.14.2

LAN (multiple subnets) : 192.168.1.0/24, 192.168.2.0/24 and 192.168.3.0/24

Remote Site:
WAN: 178.123.123.12

LAN: 192.168.32.0/24

In both places I have a sonicwall.

I created a vpn policy at the remote site as follows:
Policy Type: Site to Site
Auth: IKE using PS
IPsec Primary Gateway Name or Address: 177.10.10.2
IPsec Secondary Gateway Name or Address: 201.14.14.2

So the vpn works perfectly.

But I need to create a new tunnel for the third link pass to function as failover.
How could I solve this?

Thanks

The high level is just setup another tunnel and set the route with a higher metric so it will only work if the first route is down.

Hi aarontomosky,
I tried to create a new tunnel, but I had the following problem:

Error: Name: Address object RemoteSite overlaps in remotesite-to-site1 policy

RemoteSite is in the range of the remote network ip: 192.168.32.1 - 192.168.32.254.

Thanks
