- On the client disable the “Negotiate multi-link for single link connections” setting. To do this:
- Start > Settings > Control Panel
- Open “Network and dial-up Connections”
- Right click the VPN network connection giving the problem and select “Properties”
- On the “Networking” tab, click “Settings”
- Clear the check-box “Negotiate multi-link for single link connections”
- If the server is connected to the internet via a router then it may be that the router does not support VPN connections. Ask the server administrator to check that:
- The router supports “VPN pass-through” (be aware that different routers may use different terms). Other terms that are normally associated with this are: “IPSec” and “L2TP”.
- The router is configured to pass through VPN connections to the necessary server.
NOTE: It is not sufficient to simply forward ports 1723 and 47. Port 1723 needs to be forwarded, but what needs to be forwarded is IP Protocol 47 (GRE) not port 47. This is normally done via an explicit setting on the router. If the router does not appear to support this then investigate whether a bios upgrade is available for the router.
- Check that the server and client agree about who is assigning or specifying TCP/IP addresses. (It is common to allow the server to specify the TCP/IP address.)
- On the VPN server, make sure there are available IP addresses to allocate. The default setting for incoming TCP / IP is “(o) Automatically assign TCP / IP addresses via DHCP”. However, if there is no DHCP server on the machine, select “(o) Specify TCP / IP Addresses” and enter an appropriate name. interval.
- Check that the network protocol you are using (usually TCP / IP but can be NetBEUI) is also listed on the server side.
