Hello all,

I am trying to setup a vpn from home to my office. At the office I have a netopia router and a NT server. At home I have a win 2K network and a linksys router. I have setup the netopia router using the guides from their website step by step. When I connect the VPN, the status displays connected and the router logs display that I have been authenticated and connected. BUT I see cant see any of the office computers or the server on the office network. SO no browsing is available. Also I cant ping anything on the office network. The net use command shows none of the office computers. Also I have allowed PPTP forwarding on the linksys router and allowed ports 137-139. Any direction would be great. The are a lot of postings with similar problems that never seem to have answers so I figured I would start another to get all the new answers:)

Have you allowed TCP 1723 and GRE throught the router ?

Unable to browse through PPTP/VPN connection
Symptoms: 1. If the WINS server is on the same computer as the PPTP/VPN server, and you attempt to connect to a computer using a PPTP/VPN client, you may experience following problem: 1) The NetBIOS name of the computer to which you are attempting to connect is not resolved. 2) You may receive an error message similar to the following error message: "System error 53 has occurred. The network path was not found" when using net view or opening Network Knighthood.
2. If the WINS server is not on the same computer as the PPTP server and you attempt to connect to a computer using a PPTP client, you may be able to connect to computers on your local area network (LAN), but you may be unable to connect to network shares or resources on the PPTP server.
Resolutions: Inability to browse often means the client can't resolve NetBIOS names.
1. If this is a workgroup network, enable NetBIOS over TCP/IP on the server and clients.
2. If this is domain network and the WINS server is on the same computer as the PPTP/VPN server, move the WINS server to a different computer.
3. Add the NetBEUI protocol for your PPTP tunnel instead of, or in addition to, TCP/IP.
4. By default, most routers and firewalls prevent the transmission of NetBIOS names unless you enable UDP ports 137 and 138 and TCP port 139. Try to enable UDP ports 137 and 138 and TCP port 139 across all routers and firewalls between the PPTP/VPN client and PPTP/VPN server.
5. Make sure the client has correct DNS, WINS and Master Browser settings.
6. Make sure the default gateway points to the remote network rather than to the ISP.
7. Some ISP might block ports required for NetBIOS name broadcasts.
8. If WINS address is not distributed upon connection to VPN, LMHOSTS should be configured to enable Domain to be located.
9. If you try these techniques and the client still can't browse, try to use UNC to connect to the remote LAN, for example, use the net use h: \\servername\sharename command.
