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.
