Windows 7 , PPTP VPN error 807 and 800

[zillah]

Dear Experts

Please don't steer the topic from PPTP to IPsec and other types of VPN which is more secure than PPTP,,,,etc

I have got this scenario windows 7 is acting as vpn client at home and windows XP is acting as vpn server at work.

At home (LAN address is 192.168.[B]10[/B].x/24)And I configured windows 7 as VPN client same as here :

At work (LAN address is 192.168.[B]1[/B].x/24) I configured XP SP3 as VPN server same as here (except I could not enable PPTP Passthrough on my router because I could not find that option) :

Please be aware
On the vpn server, I have selected administrator as username to be allowed for vpn, subnet that vpn server is using, is : 192.168.1.70-73

On the vpn client I am using the correct username/password.

Security I tried below combinations with no joy:

Type of VPN : Automatic,,,,,,error 800
Data encryption: Optional encryption (connect even if no encryption)

Type of VPN: Point to Point Tunneling Protocol (PPTP),,,,,error 807
Data encryption: Optional encryption (connect even if no encryption)


Router that I am using at work (where XP is connected to it) is :

2wire router with below details :

IModel: 2701HGV-W Gateway
Hardware Version: 2701-100655-004
Software Version: 5.29.113.16

Port forwarding 1723 was enabled

Whenever I try to establish a vpn tunnel I am receiving either error 807 or 800

Note:
The VPN server (work deskto) was working when I had at home VPN client as an XP OS not windows 7, but when I upgraded from XP to windows 7 I lost my vpn connection.


Thanks

Now I have got couple of question :

1- Do I need to enable GRE Protocol 47 (PPTP Pass Through or VPN Pass Through) as well, when I read couple of online threads they suggested to enable VPN Pass Through (GRE Protocol 47) with some nasty routers

http://www.chicagotech.net/vpnsetup.htm

2- I had not enabled GRE Protocol 47 (PPTP Pass Through or VPN Pass Through)when I had XP as client before upgrading to windows 7

3- If option 1 is not necessary what could cause this problem ?

First of all. do you know the router is PPTP pass through router? If yes, you need to enable it. Please post back with the result.

I am pretty sure you meant I have to enable that for the work's router (2wire) do I need to do that for the home's router as well.

For the work's router ( 2wire) I could not find that option ( PPTP pass through router) !!!

Thanks

Sorry, you don't need enable PPTP pass through in the VPN client site. In this case, it could be firewall or 3rd party security software. Have you read this link?

Yes it is the firewall problem.

I did test :

1- On home's router cable router (simple cisco provided by my ISP) 'PPTP pass through' is enabled,,,I guess not sure the work's router 2wire has 'PPTP pass through' has GRE 47 enabled by default, and firewall (Norton 360 V4) on the VPN server (Desktop computer at work) is disabled,,,,,,VPN worked

2- On home's router cable router (simple cisco provided by my ISP) 'PPTP pass through' is disabled,,,I guess not sure the work's router 2wire has 'PPTP pass through' has GRE 47 enabled by default, and firewall (Norton 360 V4) on the VPN server (Desktop computer at work) is disabled,,,,,,VPN didn't worked

Please see the snapshot below:

From the test above now my question does that mean GRE 47 should be enabled on all routers not only a router that VPN server is behind ?


Now I have to configure Norton 360 V4 to let VPN to pass through

So, does it work after configuring Norton 360 V5 to let VPN to pass through?

Not yet I have to find out how to configure norton 360 V4 to let VPN pass through permanently

I followed the hint here :

http://www.ehow.co.uk/how_6539606_confi ... 0-vpn.html

[quote]Open Norton 360 by double-clicking the program icon on your computer's desktop or by selecting the Norton icon from the Windows task tray.[b]Update[/b] Norton 360 by selecting the "Run Live Update" menu option. Older versions of Norton 360 would inadvertently block all VPN traffic, independent of firewall rules.[/quote]
When I updated from V4 to version 5, VPN worked,,,,,,,,,,,,,,now hopefully it will keep working

Thanks
