VPN Setup w/ Lucent CellPipe ADSL Router

[SepMan76]

I am attempting to create a VPN b/w a Win2K pro and a Win2K server. I have RRAS enabled with a group policy to allow dialin for any user which is allowed dialin. The Pro computer and Server are at different locations BOTH using the Lucent CellPipe routers and have the default server for the router as the server. When the pro machine attempts to dial in, I get "No Answer". Someone told me to create a static route for port 1723 to forward to the server's 1723 port. After doing that, the Pro machine gets a "verify username and password" and hangs for a while then "Error 721: Remote Computer is not responding"...

How can I get these two computers to connect via VPN?

Please Help

We use lucent cellpipe 50a for DSL router installs, and I have only seen cisco vpn 3000 work on the cellpipe. J.Fisher CCNA

So what would you recommend? a new router or Cisco VPN 3000?

Depending on the size of your LAN I would go with a ADSL modem. No problems there with passing vpn. If not I would look into the Cisco VPN 3000. Good Luck !!! J.Fisher CCNA

I have seen this same type problem using the Linksys ADSL Router/Switch. TCP port 1723 is used by pptp to establish a session between the two machines. After the session has been established, if your doing pptp the GRE protocol is used to actually encapsulate the data. GRE is protocol 47. Both port 1723 and 47 must be allowed to pass between the two machines. You know that port 1723 is open because you get the login prompt. I would try the same thing with port 47..

sorry but I was mistaken in my last entry. GRE is a protocol, not a tcp port. 47 is the protocol type. In order to allow GRE to pass on my Linksys I had to configure the Linksys to allow PPTP passthrough. And as said in my last entry every firewall between the two machines must allow for PPTP passthrough for this to work. I would check the configuration and documentation for the Cellpipe to see if it supports PPTP passthrough.
