Gateway of last resort

I am trying to place a Barracuda web filter 300 inline. My sonic wall firewall has a 192.168.168.168 address on the XO interface and is currently the gateway of last resort on the disco 3750.  I need to change the IP on the XO interface to match the Barracuda subnet. 10.10.22.x. I created an additional VLAN 22 on the Cisco 3750 and changed the gateway of last resort to the new 10.10.22.19  XO interface. From the Cisco I can not ping 10.10.22.19,nor can I log into it, but I can ping everything else on the same subnet. No internet. I believe I am missing something on the Cisco. I had to revert to my original configuration and attached my current config files . Any assistance is greatly appreciated.

The Barracuda is a transparent device that silently watches/intercepts traffic.  From what I recall, the IP address the barracuda uses is simply to manage the device and is accessible via the Barracuda simply intercepting that traffic.

Therefore, if it is plugged inline, and it sees traffic destined to the 10.10.22.19 IP, it will respond directly to that traffic.  All you need do is have a route that says 10.10.22.x traffic needs to be routed to the 192.168.168.168 gateway, which is handled by the default route ip route 0.0.0.0 0.0.0.0 192.168.168.168.
