Sonicwall NSA-240 - Fully patched and updated.

X0=LAN 192.168.1.0 (primary site)

X1-WAN1 10.10.10.2

X2-WAN2 70.151.12.10

X1-WAN1 192.168.100.0 (secondary site)

I now have a new ATT MPLS circuit on WAN1. Traffic from our secondary site that is destined for our X0 subnet is routed over WAN1 via ATT cloud based firewall.

I need to allow all traffic from 192.168.100.0 on WAN1 access to the LAN.

I am thinking transparent or L2 bridge mode? Any help appreciated.

    Why are there two X1 interfaces?

You do not need transparent mode. Your firewall will forward traffic from the WAN1 to the LAN interfaces, assuming your policies allow it. To configure these policies, you will need to create firewall rules for the LAN to WAN and also be sure to add routes to this firewall and the firewall at your secondary site for 192.168.100.0/24 and 192.168.1.0/24 (respectively) so that traffic will route through the correct gateway.
