We did something similar with our Barracuda web filter - however, the
guest network uses the same Internet connection as our production
network.

I put up a guest VLAN that is completely separate from our production
VLANs - it terminates on our firewall, and the wireless runs on a
separate SSID/VLAN on the same switches as our production network.
That meant configuring the internal interface of the firewall as a
trunk, but it wasn't too hard to do. It also required that the
Barracuda run its interfaces as trunks - that was a bit trickier, but
their support techs worked with me, and got me beta build of their
software that supported it. That was about a year ago, so it's now
production code.

The Barracuda is a bridging proxy - it sits between the firewall and
all traffic, listening for port 80 stuff and evaluating it, ignoring
all the rest. One oddity is that the Barracuda has to have an IP
address on each VLAN. I don't quite understand why that is, exactly.

Regardless, I'm pretty sure you could do what you want in a similar
manner - the guest VLAN would just terminate on a different firewall,
or different (sub)interface of your current firewall.

So, now the Barracuda filters for both guest and production - it works
well enough.
