For 800 series, Cisco tells that they can handle up to 20 VPNs. Can I set up more than 20 static end-points (no default PSK and no end-point set to 0.0.0.0) if I think to have a contemporaneity factor less than 1? I would have about 30 end-points. Could I increase the availability of "slots" on the router decreasing maybe the lifetime periof or traffic limit?
I would know how much time after a period of inactivity the tunnel goes down. I've never seen this kind of limit while setting up VPNs on Cisco 800 serie routers..
