It was this blog entry that sent me searching from software updates that might add this feature to the RVS4000.

Does anyone have any other suggestions?

2. The setup begins with an https (TLS) authentication protocol, using the router’s PEM certificate for authentication, assuming you have sent that client certificate to whoever is going to be logging on, so they can install it in their install directory. (Otherwise, they will have to answer “no” to the question of whether to disconnect. This in turns leaves them vulnerable to a man-in-the-middle hijacking attack.) This authentication protocol is carried out with AES-256, which is certainly good, but with RSA-1024 and SHA-1, both of which are now deprecated as not being strong enough
