All,

Need your help, we have 2 sites (client and data ctr) connected with ASA IPSec VPN.  VPN Tunnel is working fine and never disconneced, and when ONE computer accessing application (say Citrix) from client site to data ctr, it is also working fine.  But when TWO computers accessing application to data center and both computer will be kicked out in few minutes, the VPN tunnel still keep alive.

Any reason for such issue, the computers in client site are connected to ASA thru an unmanagement switch/hub, will it be a reason?

Many thanks

KK
