Changed modem, internet access now blocked.

[archon79]

I am working on the following setup.

Phone Line > Modem > Server > Switch > 7 Workstations

The server is running Windows 2003 and has two ethernet ports, one to accept the Modem (incoming), the other to output to the Switch (outgoing)

Well the other day I changed our internet provider and got a new modem. But the internet does not work anymore. The internet works fine when connecting a Workstation directly to the new modem, but when you connect it through the server in the usual way something is blocking access.

I think that Win 2003 is set up in a secure fashion and something needs to be changed. IP settings? Please give me some ideas of where to start. Thanks

when you changed providers did you go from a static IP to dynamic?? check the TCP/IP settings for the Internet NIC card and see if a static IP was set or it is setup to dynamically receive an IP, when you connect the modem to a single PC and it works what kind of IP does that computer get?

Have you checked the "Advanced" tab of the new connection ? It could also be the firewall settings.
