This solution applies to Barracuda Web Security Gateway, version

When setting up the WCCP GRE interface on your Barracuda Web Security Gateway, the appliance uses the local service address (default value:  The GRE tunnel endpoint will try to route traffic to your LAN clients originating from this IP address.  

You can configure your local service address to a routable IP address on your LAN.  You can do so under the CONFIGURATION > Gateway > IP Configuration page of your Barracuda Flex interface. This IP address will be the loopback address for serving block pages and all redirected WCCP web traffic.
