We have an Sonicwall 5600 which is connected to the internet via it's X01 interface and a primary IP. We have been provided a number of IP addresses by our ISP but use no more than that first primary.
We have around 7 VPNs to various AWS instances that all use that same primary IP but we now need to initiate another tunnel using a different WAN IP.
Other than configuring another physical interface on the front of the Sonicwall, how can I achieve another sub-interface on the NSA5600 X01? I have tried Nat Policies for the VPN but it never translates from our original primary IP.
