Small VPN Question - Win 2000 LAN Access

Archived from groups: comp.dcom.vpn (More info?)

I have a small VPN set up to allow me to access my home network remotely.
The host runs Windows 2000. It has two nics, one connected to a cable modem
(named WAN) and one connected to my LAN (named LAN). The LAN uses private
IPs in the range 192.168.0.x. Internet connection sharing is enabled on the
WAN adapter. It receives an IP from my provider. TCP/IP properties on the
Incoming Connections "adapter" are set thus:

(check) Allow callers to access my network

Specify TCP/IP address: 192.168.0.101-110
(I am aware that only one VPN connection is allowed)

(nocheck) Allow calling computer to specify it's own address

I can successfully connect to the host over the VPN and I can access it's
resources, but the host computer name does not show up in the client's
network computer browser. I must manaually map a drive by using the host's
name.

I am also unable to access any other computers on my LAN. I thought that
routes between WAN and LAN would be set up automatically during the
"Registering your computer on the network" phase, but aparently that's not
so. I suppose I could connect to all the other resources on the network with
the VPN host and share them from there in order to access them from the VPN
client, but that seems really clunky.

I've tried this with Windows 2000 and Windows XP clients with "Use default
gateway on remote host" unchecked.

The following is a copy of the server and client config info and routing
tables from a console while I am connected to the VPN. Where appropriate
actual numbers have been replaced with x1, x2, etc. to indicate matching
numbers.

Would some kind soul cast an eye over this information and please let me
know if there is something obviously wrong, or what permenant routes I would
have to set up to tie the two networks together. Also, if anyone is willing,
I wouldn't mind a short explaination of reading the routing tables. I've
been through MSs documentation and have come away without learning much.
Otherwise I wouldn't be asking

I added the [??]. I was surprised to see it.

I don't understand where 4.158.x4.x5 came from so I xed it. Is this the
exterior IP of the tunnel?

I understand that this whole mess can be cured by adding a router in front
of the VPN host and getting rid of one of the nics, but this isn't an option
right now. And besides, I should be able to figure it out. Unfortunately I'm
not well enough versed in reading these tables to do so.

Thank you all for your patience. Any reply is appreciated.

You cannot enable NetBIOS with the MS PPTP VPN on Win2K.

It was deliberately crippled to force the user to "upgrade" (lol) to
XP.

I wonder how many politicians Bill Gates had to buy off to get into
this envious position.

Get rid of it. Use TCP/IP. You may think it is the same as NetBIOS,
but it isn't.

You are probably the only person left in the Windows world who has
implemented that dinosaur. Believe me when I advise you to get rid of
it. I can't see you setting up a VPN with it hanging around your neck.
