Multiple Firewalls at the edge of the network?

Hey Guys,

We have a small business of a few hundred people, they are protected with a Sonicwall 4600 series firewall.

Our ISP has given us about 15 static public IPs to use its fiber 1 gig service.

We have a very specific workflow and we need to add a Palo Alto to our network for performance improvements.

I know that our ISP has a juniper switch installed and then a device with about 5 Ethernet ports and a few SFPs.

I’m wondering if it would be possible to have both a sonicwall and a Palo Alto at the edge of each of their respective networks?

The idea would be to use a separate static IP for the Palo Alto and just install it side by side next to the sonicwall. Then go directly to the ISP device. That way the Palo Alto doesn’t have to sit behind the sonicwall.

I want to put a select few computers behind the Palo Alto because it has better performance. I don’t want to put the Palo Alto behind the sonicwall because I need real time Site to site video playback. The Palo alto handles this type of real time playback better than the sonicwall.

We dont have the budget to replace the sonicwall with an adequate size Palo Alto. So we just want to use a mini Palo Alto side by side next to the sonicwall.

Is my idea possible?
