I have just implemented a VPN connection using a Netopia R9100 router. The remote connection (offsite) to the router is working as it should - the router is authenticating the remote user. The problem is that when trying to connect to the server behind the router, the process is very slow. I am using cable modems on the client and router side, but my performance is no better that a 56K modem, probably worse. The network to which to server is attached seems to run fine with no performance loss that I can determine. The cable modems are up to speed using internet browsing as a benchmark, the pages are loading very fast on both ends. The VPN authentication to the router is very fast, and as it should be. The data through the tunnel is slow.. I can't seem to browse using Network Neighborhood, and I do have a WINS server on the LAN (not the client side). My question is; How can I troubleshoot this situation? I have called the router mfg. and they state that as long as the router is authenticating the remote user, their router is working as it should...(I'm not convinced yet) Thanks for any and all help in advance.

I'm not sure if this is your problem but sometimes the NetBEUI Protocol can cause problems such as this I would try removing it.

Some basic questions:

1. If you ping or traceroute through the vpn connection, do you get the results you expect?

2. If you attempt a pure tcp/ip operation to your network, such as ftp, does it run at full speed?

If the answer to these is "yes" your problem is probably that you are not finding your WINS server. In the LMHOSTS file on the remote computer, create an entry for the domain controller, which includes both the #PRE and #DOM: tags. This will allow the remote user to quickly find the domain controller.

Good luck.
