We have recently been enhancing the security and reliability of the support tunnel system. Something which will not be obvious to our customers is that this newer system uses two extra ports which was not required under the old system. These are TCP/8788 and UDP/8788


If you are filtering outbound connections from your SSL VPN (or any other Barracuda product) appliance, then you will need to allow these two ports in addition to any existing allowed outbound traffic in order to establish a support tunnel connection.
