Roy, A1 - without seeing the cmd script details, I can't answer that A2 - it's not clear if you're talking about the client or server side of the VPN connection with regard to the IP address change? If the VPN server IP changes, you'll have to use a dynamic DNS service to ensure proper name resoluton. and use a name; not an IP address in the connection definition. If the client IP address changes, you'll have to open the VPN acess to any remote IP address, or if you can get the IP range from the client ISP, use that list.

It is one of ideas I also have but problems are: - when create scheduled task by running rasdial command in batch file, the command keeps running when I test that batch file - The connection is PPPoE, local ISP reset/refresh dial-up connection by assigning new dynamic IP address. If this occurs at time of no client connection, how to ensure dial-up on ISA?

All of clients are shutdown in the night time, so there is no active connection from local network to outside then no trigger of dial-up connection to ISA. When ISA is reboot at such time, connection to ISA gets lot as ISA has no dial-up network. My understanding is that localhost communication to outside does not trigger dial-up connection, right? If so, what is your kind suggestion to make ISA have dial-up without any connection request from local network. With best regards, Roy Tsoa
