VPN & Linksys Router (BEFSR11)

[CLS]

Hi All,

I have setup an XP Pro VPN Server behind a router on a network at my work.
I can connect to the VPN with a 98SE box inside the network, using Dialup
Networking with the 192.168.x.x IP.

I have an XP Pro box at home. I want to connect to the XP Pro box at my
work. Whe I try to connect, a dialog box pops up saying verifying username
and password, but then disconnects saying that the network is not setup
correct.

SETTINGS

I have setup a static IP name, which I am using to connect.
I have opened ports 1723, 47,50, 51, 500, 501 (numbers which I have gotton
from numerous posts) are forwarded to the XP Pro box - All TCP & UDP except
1723 which is only TCP

Block WAN resquest is disabled
Multicast is enabled
IPSec is enabled
PPTP is enabled
Remote Management is disabled
Remote upgrate is disabled
MTU is enabled

Dynamic Routing
Working Mode - Gateway
TX disabled
RX disabled

DMZ Host - Not used - Don't want to use it

MAC Address Clone - filled in

My Home computers I have tried with and without the builtin firewall, to no
avail

Any thing that I have missed?
Thanks
CLS

assuming you got error 721. quoted from http://www.ChicagoTech.net
Error 721: Remote PPP peer or computer is not responding. If you have tried
many thing other people suggest like rebooting, reloading hardware and
re-installing the VPN or dial in connection, you still get the same problem.
I will suggest to check the router settings and make sure TCP Port 1723, IP
Protocol 47 (GRE) are opened. Also make sure that the router has the PPTP
enabled and not firewall block the traffic. On the RAS server, check the
DHCP settings.

I have heard so much on this protocol 47 (GRE). How or where can i access
it? I found all this stuff on what it is, but I cannot find anything on
where to find it or how to check it.

It's part of the VPN/PPTP client and server. You don't have to install this
protocol like you do other networking protocols like TCP/IP and NetBEUI.
You're already using it.
