Linksys WRV54G and Windows 2000 Server 4

[AndyJG]

Hi, I'm trying to establish a VPN connection using PPTP through a Linksys WRV54G router. I have enabled PPTP pass-through and port forwarded TCP 1723 to the server. When I try to connect it waits at 'Verifying username and password'. If I DMZ the router to the server then everything works, however it is not very secure.
Any ideas would be appreciated.

You need to forward another port GRE 57 (I think) do a keyword search here for PPTP ports...

[AndyJG]

Thanks Alex, it is GRE 47 not 57 and this is a protocol, not a port. This is enabled through the PPTP pass-through function of the router.

Andy,

Is the WRV54G on the VPN server side or client side? Also, when you say "If I DMZ the router to the server then everything works", do you mean when you plug the your PPTP VPN server into the DMZ port of the router on the server side, everything works? Also, what is your PPTP VPN server? Just trying to understand your config.

 

[AndyJG]

Hi, thanks for your reply. The Windows 2000 Server is behind the WRV54G router and is acting as the VPN Server using RRAS. When I try to log in remotely using Win XP VPN client, it times out at "Verifying username and password" with error 721 - "There was no response from the remote computer." When I DMZ the WRV54G to the Windows 2000 server, I connect no problem. This is unsecure though, as all ports are opened. When not using DMZ, I port forward TCP 1723, UDP 500 and 1701 to the server but don't get connected. I also have PPTP, IPSec and L2TP passthrough enabled on the WRV54G. I hope this helps.
Thanks again,
Andy

Andy,

Have you tried port forwarding UDP 47 to your VPN server (I don't think the forwarder will alow you to actually select the GRE protocol which, like you've indicated, is type 47, not port 47)? I'm not sure if just allowing the pass thru will do it.

 

[AndyJG]

Hi, yes I have tried that as well, UDP and TCP 47 port forwarded but it still doesn't work. Any other suggestions?
Thanks again.
Andy

Andy,

This is a little complicated, but here's my suggestion:

Download a copy of Ethereal (ethereal-setup-0.10.2.exe) and Winpcap (WinPcap_3_0.exe ) at:

http://www.ethereal.com/distribution/win32/

Install both packages on the client machine. This software will capture and display the actual network traffic from the cleint side. I would run a capture with the VPN server on the DMZ and then with Port Forwarding and comapare the results. You should uncover the holdup for you logon process. If you want to copy/paste the results of both captures here, I'd be happy to help you trouble shoot it.

Here are the instructs for loading/running the software.

Once the software is installed, fire up Ethereal and create a capture filter to limit packets captures with source and dest for that system alone. Follow these steps...

In Ethereal...
Pick "Capture" then "Capture filters".

Type "My IP" in filter name.
Type "host XXX.XXX.XXX.XXX" in filter string, substituting "XXX.XXX.XXX.XXX" with the clients IP address.

Press "New" then "Save" then "Close".
Press "Capture" then "Start".
Make sure you have the correct interface selected under "Interface:".
Press "Caprture Filter" then select "My IP" then "OK".
Press "OK".
You should now be capturing network data.

Next, capture data while trying to log onto the VPN server with it plugged into the DMZ and with Port Forwarding.

Good luck.

OK, here goes,

Andy,

GRE isn't getting through the router in the "with DMZ" scenerio for some reason.
After packet #8 on the "without DMZ" scenerio ( 8 0.257560 192.168.100.3 24.100.200.120 PPP LCP Configuration Request) You should have gotten a return PPP LCP like you did for packet #11 (11 3.223247 24.100.200.120 192.168.100.3 PPP LCP Configuration Request) on the "with DMZ" scenerio. So again, GRE (PPP LCP) isn't a) getting forwarded to the VPN server, or b) just flat out isn't making it through the router. Let me ask this, with the WRV54G router, can you telnet to port 8023? Some Linksys routers have an OpenRG OS that use a Busybox LASH Linux shell. If this router does then we may be able to config the unit further than the web interface will allow. Check that and let me know.

 

[AndyJG]

Hi there,
No I cannot telnet to that port, even if I port forward 8023 to the server. This is most annoying. Perhaps we can use the built in tunnel feature. I have tried to set that up but I can't get past "Negotiating IP Security" I been on the phone with Linksys support and have configured everything correctly but they cannot help.... SURPRISE!!!!

 

[woody76]

Hey Andy, for what it is worth, I have exactly the same problem (same hardware, same issue). In the same way, I can get the VPN to work only if I move the Win2K box into the DMZ. I have looked all over the net and found many people with the same problem, but no solution!

One option which we have succeeded is having a second nic on the server and place that in the DMZ. you can software filter the packets on that nic so that it only accepts PPTP.

Not a great solution, but it works. Please post if you find the answer!

 

[gacollier]

Andy,

I know this is lame, but have you tried disabling the firewall options on the router?

Also, have you tried telnet'ing to the port from the LAN side?

 

[AlexIT]

Sounds like the router is not PTPP pass-through, did you upgrade the router to the latest software version? (I know other Linksys had a bug...)

Alex

 

[gacollier]

Alex,

From the capture above, it looks as if PPTP isn't the issue, it appears to be GRE. Unfortunatley I don't think the front end on the router (web interface) will allow you to forward anything other than TCP/UDP proto's with port assignments. I'll dig around on the router and see what how to get to a command prompt for the OS.

 

[gacollier]

Andy,

I'm almost positive that the WRV54G is using the OpenRG OS. Kill the port forwarder for 8023 and try telneting to the router from the LAN side. (I'm not sure, but you may have to temporarily disable your firewall) If you can get to a command line for OpenRG you can try this:

From the web interface, create a forwarding rule called GRE for all ports using the TCP protocol. (Don't worry, we'll be changing this once inside the router)

Once at the command prompt in the router via telnet you should have a prompt like this:

SME100>

Now type/enter:

rg_conf_print /service

You should see your GRE service. Next type/enter:

rg_conf_print /service/-########/trigger/0/protocol

(where -######## is the service number for your GRE rule)
You should get "(protocol (6))" returned.

If you do, next type/enter:

rg_conf_set /service/-#######/trigger/0/protocol/47

Now, if you exit the telnet session and open the web interface and go to forwarding and view the frwarding table you shuld see "GRE" or "GRP" where "TCP" used to be. Now try to VPN through the router and let me know what happens.

 

[AndyJG]

Hi,
I still cannot telnet to 8023 even with the firewall disabled and on the LAN side.

I get "Could not open connection to the host, on port 8023:connect failed"

I'm so frustrated.

BTW I did try the VPN with the firewall disabled.. no luck!

 

[gacollier]

Andy,

Crap. Try to telnet to ports "23" or "992", again with firewall disabled. Is there not a config for remote administration?

 

[AndyJG]

There is remote management at port 8080. This is what I use to change the settings from remote using the web browser. If I telnet that port I get html code and the connection is lost. The drop down menu for remote management is 80 and 8080. If I use 80 nothing happens.
Any ideas?
