Receiving 255.255.255.255 subnet with VPN? Anyone know why?

I setup a test VPN between two Win2k server computers using RRAS. Since it wasn't actually going over the internet, I configured the VPN server as a Remote Access server, and gave it a scope of 10.0.0.1-10.0.0.4 . When I go to my RRAS server properties, it shows me the correct scope, and that the subnet should be 255.255.255.248 . When i connect and do an ipconfig of the VPN adapter address it gives me the correct IP, 10.0.0.3, but it gives me a subnet mask of 255.255.255.255 . I am not really sure how the broadcast subnet works, but wouldn't that subnet mask out all the bits so you wouldn't have a node ID? You would have a seperate network ID for each connection. Isn't your VPN like a seperate LAN all connections use the same network ID? Or is it setup where each connection should have their own network ID. I may not know enough to explain this very well, but hopefully I got the idea across. Any ideas would be great.

Seems fine to me.

255.255.255.255 mask refers directly to the host. Sometimes called a host route because there is no network address, just the host address. Check routing table on RAS server with "route print". You might see this host route there.

is it working?

it works, but 255.255.255.255 should mask out the whole host address. All that is left is the network address.

255.255.255.255 is a special case and specifically refers to a single host. Lots of RAS servers do this to make routing easier for the remote host and also ease summarization of a large number of remote hosts
