I am having an issue with one of my remote sites. We are creating a VPN tunnel from a PIX 501 (remote site) to PIX 515 (corporate office). Initally, the vpn tunnel is created and the users can access resource on our corporate network (i.e. email, files, printers, etc.) but after closing outlook or letting the system sit awhile, I lose the vpn tunnel and the only other way to re-establish the connection is to power cycle the PIX 501.
Any advice would be greatly appreciated
