VPN Error 800

I am continuously getting an Error 800 return code from both the Connect to Small Business Server client and an XP VPN connection. When I am trying to run from the lan, then I can connect just fine using any method. The server has 2 nics and wan is directly connected to internet without a router or firewall. I have tested the connectivity by running PPTPSVR on SBS 2003 and PPTPCLNT from XP from outside the lan. It tells me that the protocol 47 is passing through without any issues. I am also connecting and the details below will show you how:

Netstat shows pptp LISTENING and ESTABLISHED as I've made two attempts to connect from outside.


C:\Documents and Settings\Administrator>netstat -a | find "pptp"

Now I connect from inside. Note that HOME is the workgroup name of my laptop

C:\Documents and Settings\Administrator>netstat -a | find "pptp"

Note that the RAS Server has started as part of the inside connection.This did not occur when I attempt to connect from outside.

Now the name of the workstation appears (it's changed from the name of the workgroup)

The Remote Web Workplace works just fine both inside and outside.

I have attempted this with the firewall on the WAN disabled. I am NOT running ISA. I have run the wizards MANY times. Can anyone tell me why is this not working?

Even I am facing the same issue with a similar kind of setup. I needed to disable the RSS on both the external and internal NICs to solve this issue. It will say that its for people with ISA but I didnt have ISA installed and still had the issue?

The error 800 means that it cannot find your VPN Server. When you run the Remote Connection Wizard then a FQDN that points to the external IP of your SBS box in your notes remote.yourdomain.com should point to the external IP of you SBS box. You are also saying that you are not running a firewall in the beginning and then the last sentence you say that you have disabled it? If you do have a Firewall 1723 and GRE must be open. I think that your ISP can block the 1723 but can you connect externally with telnet externally 1723?
