Re: Home VPN

Okay, I tried a remote ping with XP server connected directly to internet,
and it failed. Strange, even though it failed, I can make a VPN connection,
however, RDP will not work over the connection. After beating my head up
against a wall for a week now, I find the Windows XP usage as a VPN server is
problamatic, to say the least. TightVNC is looking pretty good now. If anyone
can advise me of a step by step config of XP for VPN server, please let me
know.

Okay, PPTP ping is not passing through. On the server end I get a message
"Erro 10048 binding socket: WSAEADDRINUSE: Address already in use, Created
socket for GRE protocol test, Listening on PROTOCOL 47 for incoming GRE
packets..." and on the client side "ERROR 11004 getting host information:
WSANO_DATA: Valid name, no data record of requested type". Tomorrow I will
try remotely without router and see what happens. Thanks.

They look Ok to me... Run the test to make sure the router is or is not
passing GRE traffic...

Sooner Al, I downloaded the pptp ping test software as per
recommendations,
however, before trying it I brainstormed myself into connecting this
machine
directly to the internet instead of through home network, and was able to
make a VPN connection. So it appears the router is the problem. I have
contacted LinkSys, and they tell me the router should pass through PPTP
GRE
47 protocol and I have the latest firmware. Did all of my interal IP
addresses appear correct to you? If so, I may have to replace my router.
Thanks in advance.

You can run the "PPTP Ping" test detailed on this page in an effort to
troubleshoot this problem. Its possible your router is not passing GRE
Protocol 47 traffic. See the "PPTP Ping" and the "VPN Traffic" sections.
Run
this from a remote PC, ie. laptop or desktop, through the router.

A firmware upgrade may or may not fix the issue if in fact the router is
not
passing GRE Protocol 47 traffic. An alternative may be to use OpenVPN
(that
is what I use) or Secure Shell (SSH). Both OpenVPN and SSH use one
standard
port, configurable I might add. OpenVPN uses UDP Port 1194 by default
while
SSH uses TCP Port 22 by default. Both can be configured to use an
alternate
port...

I am unable to establish a VPN connection to my home Windows XP Pro
machine;
however I can connect using Remote Desktop Web Connection. But I need
to
be
able to map my hard drive remotely to exchange files. My network is
connected
to an always on cable connection. Here are my settings; I have a
Linksys
wired/wireless router with local IP address 192.168.1.1 subnet mask
255.255.255.0 with VPN pass through enabled and port 1723 and 3389
forwarded
to 192.168.1.20. My LAN TCP/IP settings are IP address 192.168.1.20
Subnet
255.255.255.0 Default Gateway 192.168.1.1 DNS Server Address
192.168.1.1.
I
have the incoming connection set for VPN to Assign TCP/IP address
automatically using DHCP; I have TCP port 1723 and 3389 opened in
Windows
Firewall. And of course I have Remote Desktop enabled in System
Properties,
and have appropriate user name and password. It appears that VPN passes
through the router but is unable to authenticate with the computer.
While
verifying username and password I get an error 721, unable to connect
to
remote computer. Any insight would be appreciated.
