Bypass VPN (use real IP) for certain websites or remote IPs.
- If a certain website is blocking access to foreign IPs, so you can only access it with your real IP.
- If websites and services forbid the use of VPN, so your account won't get restricted or suspended.
- If you cannot access a local machine in your network while the VPN is connected (e.g. server, other computer or network device of any kind).
On windows, to create static routing rules to let IPs bypass the VPN, you need to use the integrated tool "route.exe" of Windows. You can find it in the folder C:\Windows\System32 - but it's executable from any place.
To use it, open a command prompt. Run "cmd.exe" or navigate to "All Programs/Accessories/Command Prompt" in the start menu. Run "route" to get the instructions for how to use this tool. How to use it for our purpose (IPs bypassing the VPN) is quickly explained:
1) First you need to find your gateway IP address. This is usually the IP of your router/DSL-Modem, so the device your computer gets the internet from.
If you're not sure which IP that is, please run "route print". In the mid-section of the output, you should see something like this:
2) You'll see that certain IPs are using a gateway address that belongs into your local network. In this case, 192.168.88.2 is our gateway IP address, the IP of the router.
3) Keep that gateway IP address in mind. Now we need to get the IP of the website you want to bypass the VPN. For testing, we can use http://ipaddress.com.
4) As you might know, this website shows your current IP and location. When disconnected from the VPN, go there and you'll see your real IP and location.
5) To get the IP of that website, you can simply ping it by running "ping ipadress.com". It returns the IP address, which is: 126.96.36.199.
6) Alternatively use websites like this one for this purpose.
7) Now we create a routing rule for this website, by running "route add 188.8.131.52 192.168.88.2" (syntax: route add destinationIP gatewayIP).
8) When that is done, connect to the VPN and visit http://ipaddress.com again. You'll notice that it still shows your real IP and location, instead the VPN IP and location. That means the routing rule is working and the website is bypassing the VPN.
Note: This rules are only temporary, that means they disappear upon next reboot. To make them permanent, use the switch "-p", so e.g. "route -p add 184.108.40.206 192.168.88.2".
Mac OS X
The setup is pretty similar to the manual setup with route.exe in Windows, just the commands differ a little. To get the current routing table, so you can see all existing rules and get your gateway IP, run: "netstat -r". The output should look like this:
You can see that the gateway in this example is 192.168.132.2. OK, now let's create the routing rule.
In this example we also want to let ipaddress.com bypass the VPN, so we need to get the IP of that website by pinging it. Run "ping ipaddress.com". It returns the IP of that website, which is 220.127.116.11.
Run "sudo route -nv add 18.104.22.168 192.168.132.2". The syntax is "sudo route -nv add destinationIP gatewayIP". The output should look like this:
Now, connect to the VPN and visit http://ipadress.com. You'll notice that it shows your real IP and location, instead of the VPN ones. That means the routing rule is working and the IP/website is successfully bypassing the VPN.
How to creating routing rules on Linux differs from distribution to distribution.
For an overview and a detailed explanation for each distribution, see this link.
The command "ip route show" shows your current routing rules.
To set up static routing rules on Android, your device needs to be rooted. Then you can use any terminal emulator (e.g. this one) to get into the command prompt.
To get root privileges in the command prompt: su
To show the current routing rules: ip route
To set routing rules, you can use the same instructions as for Linux. See the link above.
