Roadwarrior VPN Disconnect?

kwermann
Hi All,

I have a remote IPSec Roadwarrior connecting. Every few hours they loose their VPN connection. Here is a segment of their logfile from ASC:

9/7/2006 2:43:02 PM  IPCP  - connected to vpn with IP Address: xxx.xxx.xxx.xxx. : xxx.xxx.xxx.xxx.

I disabled Dead Peer Detection at the firewall. Shouldn't the device stay connected? Do I need to modify the SA LIFETIME's in the Firewall, and/or ASC?

Any help is appreciated.

Thanks,

Ken
