Can't estabilish PPTP to DIR-330
« on: January 19, 2009, 01:24:39 PM »
I've been trying to connect my home computer to my office router using PPTP. The dial-up screen stops when trying to verify username and password then disconnect. Below is the descriptions of the environment:

  • My home computer is running on Windows Vista Ultimate SP1
  • My home router has been configured to allow VPN Passthrough
  • Port 1723 is opened on my home router
  • My office doesn't have static IP so I signup Dynamic DNS service

I would like to know if I did something wrong and thanks in advance for any help.

If the DIR-330 your router or is it behind your router?
     (These assume it is behind your router)
     What is your router?
     Why is your DIR-330 behind your router?
     What is the LAN Net on your DIR-330?
     What is the LAN Net on your router?
What settings do you have set for your PPTP Profile?

The DIR-330 is located at my office.
At home I'm using a Linksys router.

Sorry for the mixed up...

If you connect directly at home (minus router) can you dial in?

What are your full PPTP settings, most notably NAT-T?

I'm not sure what is NAT-T.

Here's my settings for the DIR-330 at my office:

  • Connection Type: PPTP
  • VPN Server IP: 192.168.1.1 (DIR-330 IP)
  • Remote IP range: 192.168.1.110 - 120
  • Authentication Protocol : MSCHAP v2
  • MPPE Encryption Mode : 128bit

Settings for my Linksys router at home:

  • Port 1723 forwareded to my desktop
  • UPNP enabled

Ignore the NAT-T I had myself turned around, it is an IPsec setting.

Can you connect minus your home router?
