USB firewall

Howdy

I have a linkzone 2 from calyxinstitute.org, it is currently my modem, firewall and router. Its working great but the firewall port forwarding feature is to limited for what I need.

I'm looking for a solution that will allow me more sophisticated firewall features.

I know replacing my linkzone with a different router is an option but I don't want to go that route since its against calyx policy.
I found this sonic wall solution that sounds great.

It wants me to disable the wifi on my linkzone and tether it to the sonicwall firewall device. From there I could go to a router and done. My only issue is I think this sonicwall device is overkill for my needs. I'd rather not pay $250 if a $50 device does the trick.

I found this $99 device but I'm not sure it will work with the linkzone2

Does anyone know of a firewall device for under $100 which will work with the linkzone2 and allows port forwarding of a range? Not just a single port

Thanks!
