Split WAN with mulitiple public IP address

I have SonicWALL Firewall/Router and 5 public IP address. I am going to have 1G Fios connection soon; however, the my soniwall won't give the 1G connection speed due to the DPI.
I would like to create second network that outside of firewall and wondering if I can split by public IP address with separate router.  Do you have any solution for this?

Hi MoonLive,

Yes, you can do this a couple of different ways depending on your provider and how they are delivering service to you. If you have independent ISPs then you don't need any additional equipment provided that you have another firewall for the new ISP connection.

If the same ISP is providing both circuits on independent services like Bonded T1 and Fios then again you can achieve this by doing as I previously mentioned.

If the same ISP is providing both circuits on the same service like both Fios (assuming 1 Ethernet hand-off) then you'd put a managed switch upstream from the SonicWALL and then split the different IPs to separate ports so the traffic will reach the other firewall for the corresponding IPs.

Let me know if you have any other questions!

Blue Street Tech, Thanks for the quick reply.  Verizon delivers the 1G fios here and it is upgrade so there is no "separate" circuit. Connection from Verizon goes to Sonicwall and i can assigned one of my unused public IP address to the port (such as X12) as public IP address?
if that is true, isn't still goes to Sonicwall? I am trying to by pass the Sonicwall. Thanks for your help!

Yes, as I said above "If the same ISP is providing both circuits on the same service like both Fios (assuming 1 Ethernet hand-off) then you'd put a managed switch upstream from the SonicWALL and then split the different IPs to separate ports so the traffic will reach the other firewall for the corresponding IPs." This will bypass the SonicWALL. Here's an example:

                             FIOS
                          1.1.1.1/29
                                |
                       Managed Switch
Port G1: 1.1.1.2                 Port G2:1.1.1.3
              |                                        |
       SonicWALL                   Another Firewall

Does that make sense?

The only issue is having the ability to LB (Load Balance) the other Firewall so one network doesn't over-saturate the other. Ideally the LB should be upstream from both firewalls but depending on the size of the network you can achieve it by implementing LB in both firewalls - essentially traffic shaping and throttling.
