Preventing Dynamic / Temporary VPN Interfaces

I’ve been fighting to find a solution for a while now (search wasn’t any help).

I use static VPN bindings for all my links. One of my point-to-point VPN connections is a bit unstable. The client Routerboard automatically re-establishes the connection when the link fluctuates, but when it does this before the server Routerboard closes the connection, the server creates a dynamic/temporary interface which messes with the routes, firewall rules, etc.

Is there any way that I can prevent the server RB from creating temporary interfaces, and forcing it to the the server binding, and rejecting requests for the extra second or two till the correct static binding has been freed? This isn’t a proper fix for my problem, but it will help lessen the impact until I get the connection sorted.

Thanks!

Hi Juan,
I have the same problem.

Did you find any solution?

I’m not sure if this will help in your situation, but we do something similar for our VPN network. I resolved it for us by setting the client profile, under limits, to allow only one connection.

Thanks zennik,
I selected “only one” property on server PPP profile. This should have an effect on all clients. Last few days I test this, work fine until now. But the problem happens rarely (maybe once on week) and I need a lot of time to do correct test. After month I will post here results.
