I apologize to be opening another question with such a similar title, but

PPTP VPN - users cannot access internet via the server

does not quite cover the issue I'm encountering.

I have a VPN Server setup through Windows XP. I can successfully connect to this VPN from outside my network using PPTP. However, when I try to access a webpage, it times out. When I run a tracert, I get the following result:


I have verified that "Use default gateway on remote network" is CHECKED. It does appear it can connect to the VPN, but times out getting any further.

Thanks for any assistance!

**1st Edit:

**2nd Edit:

I've enabled TCP/IP routing per this guide: http://support.microsoft.com/kb/315236

I'm using a WRT160 Linksys router.

**Final Edit:

The issue came down to specifying an IP range within the router's valid IPs. For me this meant changing to and then for the end of the range. Enabling/disabling IP routing did not have an effect.


You probably need to verify on the pptp server that it is correctly configured for

  1. routing packets
  2. nat-ing traffic
  3. allowing such traffic

Update: after discussion, what solved the problem was:

  • configuring the network range for the vpn clients in the same subnets as the one handled by the router which provides internet access.

    • Surprisingly enabling routing on the xp box does not make any difference!
  • I sure do! I also have access to the router that the server is sitting behind, which is a WRT160N. Just let me know where to start looking and I'll post edits to the question with the related info. – Nick Heidke Feb 16 '12 at 15:14
  • Ok, what kind of server is it? Windows or Linux? – Olivier S Feb 16 '12 at 19:50
  • It's actually a Windows XP machine, I used this guide to get this far: onecomputerguy.com/networking/xp_vpn_server.htm – Nick Heidke Feb 16 '12 at 19:54
  • I did not know XP was able to act as a VPN server. I suppose that you have to enable routing on it: support.microsoft.com/kb/315236 . Hopefully it will make it work – Olivier S Feb 16 '12 at 20:40
  • by the way, what range of IP addresses does your vpn server give to remote client? Did you opt for dhcp or did you specify a range yourself? – Olivier S Feb 16 '12 at 20:43
