Re: Can't login Win XP to XP via VPN

Well, I thought you were talking about running a PPTP VPN server on an XP box (either behind a NAT or directly connected to the public internet) with an XP client? That definitely works. I have never been able to figure out how to run a L2TP/IPsec server on an XP box. I don't think you can. Beyond that L2TP/IPsec and PPTP are two totally different VPNs so that has no bearing on PPTP anyway.

If you can't get PPTP VPN to work then alternatives include

* changing your router to one that is known to support PPTP VPN pass through

* upgrading firmware in your router to a version known to support PPTP VPN pass through

* use third-party firmware like DD-WRT (which includes a built-in PPTP, OpenVPN or SSH server function) on a supported router

* Secure Shell [SSH] (which in my opinion is very easy for home users to setup and use) on a XP/Vista server PC

* OpenVPN

* SSL-Explorer

* setup a Windows Home Server at home

* use a third-party solution like Hamachi

Personally I have used all of these alternatives excluding Hamachi. I currently run a Windows Home Server [WHS] and have access to shared files/folders on the WHS via a SSL VPN tunnel or desktop PCs on my LAN via the WHS Remote Desktop proxy.

Thanks Al,

I can't get my srv & clnt to give your results ...
But now I read here: http://support.microsoft.com/kb/818043

Excerpt: By default, Windows XP SP2 no longer supports IPsec NAT-T security
associations to servers that are located behind a network address translator.
Therefore, if your virtual private network (VPN) server is behind a network
address translator, by default, a Windows XP SP2-based VPN client cannot make
a L2TP/IPsec connection to the VPN server. This scenario includes a VPN
server that is running Microsoft Windows Server 2003.

Does this mean that the microsoft VPN client can't connect to a Win XP that
is behind a router with nat (as mine is?
