Applies to all Barracuda SSL VPNs.
When Network Connector publishes its routes to the client to tell it how to route data to the main LAN, then the client will lose access to the main public IP. The issue will occur when a client connects to an SSL VPN that is on a public IP. This is known to commonly happen on Windows XP clients but has been seen with some other operating systems.
For example, we have public IP 22.214.171.124. The client needs to be able to route to this obviously, but when the NC client starts, it gets a command to route that subnet via its virtual IP that Network Connector assigned to it. This route conflicts with the requirement for the client to be able to connect directly to this IP.
Barracuda Networks Technical Support can activate a workaround that will push another route which tells the client machine that for this specified public IP address ONLY to route back through the client’s default gateway and NOT the virtual IP.
