I have a gateway to gateway VPN setup using a Cable modem to ISA server which is connected to nic card (external) the other nic card (internal) is connected to switch (hub)which the clients connect to at the branch site to our main office using ISA server on both ends. the VPN connections works great EXCEPT it disconnects in 2 minutes or less. event logs an error of 11005 which i really do not see as relavent. also the branch sites ISA server acts as the dhcp for the clients. Any ideas??? Angelo Hi Angelo, Does the connection automatically redial? Are both side "active"? YES to BOTH
