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.

  • Just to clarify and simplify, you have two different, non-sequential blocks of IP addresses coming in over a single connection to the ISP correct? Apr 29, 2014 at 13:00

See this knowledge base article for details, but basically:

  1. Create a Static ARP entry for the new network.
  2. Create a Static Route

Needed to add a static arp entry and static route for 2nd set of public IP addresses.
