newly disovered interfaces?

Hi

I have a router that acts as a VPN sever too. I have very strictly only exported netflow data for 7 of the router's interfaces. The data is analysed wonderfully and it is working flawlessly.

HOWEVER

Everytime a VPN user connects and a new tunnel is created, it seems that NetFlow Analyzer then picks up the Interface via SNMP, and adds the Interface to the router automatically. NOT the desired result unfortunately

Is there any way that I can stop this behaviour, or any way at the very least that I can tell NetFlow Analyzer to put any automaticaly discovered Interfaces into UnManaged mode?

We're currently using a eval, SERIOUSLY considering to buy licenses for at least 50 interfaces (multiple routers). But I can see that these VPN Tunnels are going to cause absolute havoc in terms of any possibility of buying licenses... I have no control (except to manually go and change settings the whole time) to tell NetFlow Analyzer not to manage these interfaces. It's a bit of a pain!

Thanks! :)
Chris.
