I have some users out in a school district that need to VPN to our system. All of the internet access for all of these schools goes through one proxy for the whole city.
Currently I have a ISA server that they connect through via PPTP but the issue is that not more then one person can connect at a time as they are coming from the same public IP address and ISA does not seem to handle it.
I am looking for any solution for this situation. Can other VPN Appliances handle this type of connection?
We cannot put in a VPN device that all the users would connect through as they are at different physical locations in the city.
Thanks for the help
