I'm a VPN beginner interested in setting up a permanent VPN connection between two facilities. I have a 1720 router on one side. Would it be best to assume that a second 1720 router at the other end would provide the best result?
Is it a bad idea to use long-term VPN links?
Also, are there any security pitfalls particular to the 1720 that I have to watch out for in doing this?
I have a question about a long term VPN I'm running, linking two of my sites like this, with a PIX and ASA.
I want it to stay up forever. Do you know if the tunnel absolutely has to renegotiate after a certain number of hours in operation or something like that? We have a server process running across the link to some devices (like a similated serial link). If the network resets, it kills the process.
It is my understanding that an essential part of the IPSec implementation is the concept of the lifetime of the Security Association and so yes it is essential for the tunnel to renegotiate. In my experience usually the negotiation of a new SA takes place before the existing SA expires and the transition should be transparent. Is that not the case for your VPN?
