    If you connect using the computer with the PPTP client configured without the other computer with the VPN client connected through the server are you still experiencing the same problem, this is just for isolation if it does work, your router only support single VPN client passthorugh(most SOHO routers only supports single VPN passthrough not simultaneous).

Security concerns & VPN settings


You understand correctly. Your traffic from you to Golden Frog is encrypted both ways - that's why it's called VPN Tunnel. This way the traffic appears to come from them and not from you, so you can't be traced back easily. I say easily because there are ways, but then we're talking about serious knowledge and effort. Think "James Bond" - nothing for the "Household Hacker".


As encryption protocol you should definitely use L2TP with IPSec.

In general there are three protocols: PPTP, L2TP/IPSec, and OpenVPN.

PPTP uses 128-bit RSA encryption, the latter two 256-bit AES. I would choose OpenVPN over L2TP because of the lower overhead and therefore less stress on the CPU when encrypting data.

You should steer away from PPTP since it has serious security issues. First the encryption is done in one step compared to the two-step process in L2TP. Furthermore PPTP is a proprietary protocol using Microsoft's Point-to-Point Encryption protocol MPPE implementing RSA RC4 algorithms.


L2TP on the other hand is using the standardized IPSec protocol. RFC 4835 specifies either the non-proprietary 3DES or AES encryption algorithm for confidentiality. iVPN uses the AES algorithm with 256 bit keys. (AES256 is the first publicly accessible and open cipher approved by the NSA for top secret information.)


If you want to read more about PPTP vulnerability, you can find it here.


Your impression of torrents is not totally correct. The software itself is not virus infected and has it's legitimate use. Example: Most Linux distributions are available as torrents. The reason is that instead of 100,000 people downloading the image from one server, the image is shared between many people, therefore easing the load on the server and keeping the cost down, since you have to pay for traffic as a host.

The general problem with torrents is that they are often used for sharing illegal content or files, usually where the source cannot be determined with certainty. You should always treat downloads from the internet and/or unknown sources with suspicion and let your AV software run a scan.


Any general advice?


One big one for me is to never use Windows OS for my online banking. I might be paranoid, but then I think I worked too hard for my money and rather go through the inconvenience than through the "pain".


General information can be found here.

A wiki containing a list of banks and browsers supporting Linux is here.

A distribution especially designed or online banking called "Bankix" can be found here. The article is in German, but can easily be translated through Google. The main advantages are:

The internal hard drive is not accessible thanks to a patch to the Linux Kernel and the boot media is secured (prevents against Zero Day Exploits.)


Hope that helps.

The router's PPTP passthrough and IPSec settings assume that you're connecting to an external VPN server on the public side of the network, but it sounds like you're hosting your VPN server inside your local network. If this is the case, you may just want to have your windows VPN box in a DMZ, or get a router that you can exert more control over. Be wary, if you're doing this at a residential location, your internet provider will probably block or "shape" this type of incoming traffic to your local network.

I am having problems connecting VPN Connection on my Windows 7, it says there need to be a machine certificate installed before i can connect using L2TP/IPsec. error code :766


"Error 766: A certificate could not be found. Connections that use the L2TP protocol over IPSec require the installation of a machine certificate, also known as a computer certificate."

"Error 766: The L2TP connection attempt failed because the security layer could not authenticate the remote computer."

Cause: Connections that use the L2TP protocol over IPSec require the installation of a machine certificate, also known as a computer certificate. You will see this error message when such a certificate is not available.

Typically, this error is generated on a remote access server that has active L2TP ports configured, the remote access service started but there is no certificate in the computer certificate store. This generates an event log message that tells the administrator that L2TP ports will not be able to accept calls until a certificate is acquired and RRAS is restarted.
Resolutions: 1. If you use PPTP VPN, select Automatic in Type of VPN.
2. If you use L2TP, check the remote access server and make sure there is certificate in the computer certificate store.

Problem connecting to VPN (PPtP) via DIR-655


pimrakers

Since it work when directly connected to your modem then most likely it is an IP issue. With VPN you router can not be in the same subnet as the one you are connecting too. So alot of places do not change the IP's the equipment unless they have to you just got lucky and a router with the same default settings. If you change the IP address then you should be able to connect. Note you should only have to worry about the last 2 number sets. Example if your routers IP is 192.168.1.1 then I would change it to 192.168.5.1. Just remember what you changed it to. Also you can use any number between 1 and 254.

Let me know if you have any more problems or questions.

Belkin F5D9230-4 won't allow a connection to M Exchange server


Login to your Belkin router and check to see if there is a firmware update available for your specific model. If so, download and install it as this may resolve the problem without doing anything else. (Be sure to save your configuration first)

The specifications for a F5D9230 state that it supports VPN passthrough so you shouldn't need to configure anything in the router itself. It may be necessary to open a few incoming ports but only as a last resort.

Would you also reply to this post and specify...
  1. What OS are you running on your pc?
  2. What VPN client are you using on your pc?
  3. Ask the administrator of the Exchange server if they're using PPTP or L2TP for VPN connections.
Another option would be to use OWA (Outlook Web Access) to access your email if it has been installed on the Exchange server.

- Check the Internet if working properly?
- Access the configuration page of your router and open the firewall settings, uncheck the list below:

Enable PPTP Passthough
Enable L2TP Passthough
Enable IPSec Passthough

- Try to gather some VPN ports to open using the router.

Note: You should have your permission from the connection of VPN to use it.

VPN Using XP Servers and D-Link WBR-2310

DLink DI-624s - can't get Cisco VPN Client to connect.


The "Virtual Server" setting is designed to give the general public access to a network resrouce (web/ftp/media server) on your internal network. If your the VPN concentrator is external to your network (meaning you'll have to use the internet to connect to it), then you won't need to define a virtual server on the DI-624.

You'll just need to enable the IPSEC and PPTP VPN Passthrough which it sounds like you've already done this. I've run into some ISP's that block VPN connections out of their network. If you have the ability, try to directly connect your laptop into your cable/DSL modem in place of your router and see if you can make a VPN connection, if not contact your ISP, if you can then verify you enabled the VPN passthroughs because your router is blocking them.

GIve it a shot and let us know your results.
