I have a Sonicwall NSA 3500 firewall. I have a primary block of public IP addresses that are working fine but I need to utilize a second block of IPs that are routing over the primary from the telco side. Does anyone know how to configure this on a sonic wall? I am not finding much info on it. I have done the NATing and firewall rules etc but I don't see a place to configure the gateway on the firewall for the 2nd block of IPs.
