Adding a Secondary WAN Subnet to Sonicwall and a Cisco


Current WAN IP range:
Sonicwall WAN IP: 
Cisco Router:         
New WAN IP range:

You can add a static ARP entry on the Sonicwall but there is an easier method. Simply set a static route on your Cisco router.

# ip route

Then on the Sonicwall, just set up the address objects, NAT policies and any firewall rules that you need.
