I am trying to resolve an issue whereby a Windows 2000 RAS Server is not allocating a default gateway to clients, and hence they can't get Internet access via the corporate network.
When I connect a client via ISDN or Modem dial-up, ipconfig states the subnet mask of the connection as 255.255.255.255, and the default gateway is the same as the IP address assigned to the dial-up client.
Computer Name: RASSERVER
Static IP x.x.x.21
DG x.x.x.130 router to US office
We also have a Firewall x.x.x.10
Setup as a Remote Access Server only.
Enable IP Routing is ticked
Allow IP based remote access... is ticked
Static address pool is defined
General ->Loopback, LAN and Internal. Enable IP Router Management and Router Discovery options both ticked for LAN and Internal interfaces.
Static Routes -> None defined
IGMP -> LAN Connection is enabled as proxy. Internal enabled as router.
Apparently this was working before the firewall was put in place. But now is not. I imagine its a routing thing but not too sure. The firewall is managed by a third party.
