We're starting to get some international customers.  I want to understand what kind of latency an IPSEC VPN can tolerate on the internet connection before it stops working.  Any opinions/experience?

Thanks

Patrick

Latency for the IPSec tunnel should not matter much. It effects the traffic that is flowing through the tunnel. You need to make sure that the path between the 2 peers is not dropping any packets as that will cause you to loose DPD (keepalive) packets, that will take the tunnel down from time to time.
