Can't maintain TCP/IP communications with Windows Dial-Up Networking client

[kevtown]

I am setting up a Cisco 2509-RJ to provide Dial-In access for Remote Windows Dial-Up Networking Clients. So far the client can connect, authenticate retrieve a DHCP IP address, DNS, and WINS settings, and even utilize TCP/IP network resources for almost exactly 2 minutes. However once those two minutes are up all TCP/IP communications fail. The modem remains connected and the client still registers sending and recieving bytes with the Access Server until I force it to disconnect.

I haven't discovered any timeout settings on my client or server that are set at 2 minutes. If anyone has an idea as to what might be causing this I would appreciate some guidance.

Thank you,

Kevin Townsend
