Easy VPN client is running on C800s and tunnels to a 3K concentrator. We have approx 400 remotes up at once. Several times over the course of a week an IPSec tunnel is lost between the 3K and a client. Appears random. Don't know which device is causing the problem.
The keepalive setting on the remotes is 10 sec. I think on the 3k it is 2 sec. I looked at the text version of the 3K config file which showed: keepaliveinterval=2. I don't know how to find the keepalive value using WebVPN, I just know that the keepalive box is checked. Anyhow, what problems could be caused by this mismatch in keepalives if any? Any comments, explanations or references are appreciated. Thanks
