Sonicwall Routing

I have a scenario where I am currently using a WAN connection on my TZ210 to a network "above" mine that provides access to necessary servers as well as the Internet. Currently, I have about 75 one-to-one NATs for various internal static IPs to external static IPs, which are necessary for the server communications. I am getting my own Internet connection, however, and would like to route all 10.168.0.0/255.255.252.0 traffic through the primary WAN connection (the current one) and then route all other Internet-bound traffic through the secondary WAN connection (the new one). What is the best way (most efficient) to do this?

Source based routing would be an option where you can select packets originating from a specific source to use a specific interface to exit.

Thanks for the comment, Andrew!

Would that require changes to Routing, NAT Policy, and Firewall? That is what I had in mind, but I wasn't sure #1 if that was the most efficient way to handle it and #2 if it required changes to all 3 sections of the Sonicwall config or just the Routing. It seems, though, that all 3 would be required.

I just thought of this as well: How would I route all other traffic through the new WAN connection?

Thanks for your advice, Andrew! Sorry it took so long to respond. I must have missed the email to inform me of your reply. I am going to reconfigure the entire router sometime in July probably. I plan to setup the new Internet connection on the primary WAN (X1) and setup the (X2) port as a trusted LAN. Then, I will setup source routes to route all traffic destined for 10.168.0.0 through the X2 port like you suggested.
