Server 2003
multi homed

RAS interfaces were changed for new nic

Make sure the switch settings changed as well to accomadate for the 100Mbps full duplex capabilities of the new nic.
Also make sure the mtu is ok as well. Did you connect it back to the same switch port?

Some ISP's will change your IP when your MAC address changes, as which happens when you change NIC's.  Verify that the IP is still the same.

I know several providers of Broadband in my area that have what's called persistent IP's.  As long as the MAC doesn't change, the IP won't.

Pluged back into the same port.
We have a static IP so that has not changed
Not sure wher to check MTU . It is not in the NIC properties.

Try to ping it to check whether it's VPN (security) or connectivity problem. If you can then check your RRAS VPN settings. Could be MAC filtering or other issues. Check any ACL (access list) on the switch / router / firewall for MAC filtering. Try to start any simple service like telnet on that NIC and see if it works.

Figured it out! I did not have the services and ports configured for the nic  under NAT / Basic Firewall. VPN Gateway and IP Security must be selected.
Thanks for the help.
