Re: VPN 3015 consentrator to Clinet connection lost
We saw the same problem. The only way around it that we could see was to disable IKE keepalives for the group and then hope that the idle timeout will disconnect those clients that have been rudely dropped but are still listed. This has fixed most of the disconnects we were getting and I haven't had anymore complaints (we get ~25 users connected at any one time). I use it about every day and havew only been disconnected once in the last 2 months.
We figured that the IKE keepalive packets were getting lost or dropped when a dial up client was busy doing other things and had pretty much filled up its pipe. You may want to check the bandwidth on your internet connection as we had to upgrade from a T1 because of the number of Cable/DSL users working from home.
