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?
