What is a VPN Passthrough?


VPN Passthrough is the router feature that allows private network computers to unhindered set up outbound VPNs. Incoming VPNs have little to do with the Virtual Process Networks. This term is originated from enabling the router to “pass” the traffic of VPN. No terminals need to be opened to allow the VPN passthrough, because this operates automatically.

First of all, you have to understand the two types of routers.

  1. 1st type of router recognizes a VPN connection like PPTP, L2TP, or IPsec. You may set up this router with some other VPN gateway to function as a VPN server, or a site-to-site VPN can also be created.
  2. 2nd type of routers is not designed to work as VPN servers. These routers do not support such technological advances, so you’ve got to work around this one. You can accomplish this by using the passthrough feature. When you activate this feature, VPN client traffic goes through the internet and immediately arrives at the VPN gateway.

So, one kind of router supports the VPN connection, and the other types of routers do not recommend this connection. VPN passthrough is required for those routers which do not support a VPN connection.

How Does VPN Passthrough Work?

VPN Passthrough means the ability to reach a VPN server. Your router can enable packet headers from a VPN client to transfer through it. Routers mostly use the technology NAT, which is Network Address Translation. This feature allows for all the devices which are connected to the same network can use the same IP address and connection.  

The VPN protocols like IPSec, PPTP, and L2TP do not work with NAT. To work with these protocols, you have to use VPN passthrough technology. By using the interface of their router, users can disable or enable IPSec /PPTP / L2TP Passthrough.

Why should we use VPN passthrough

  • VPN passthrough is like a firewall that is used by the routers. It allows all the connected devices of the same network to use the same internet, and they can also share the same IP connection.
  • The IPsec and PPTP protocols do not work correctly with the NAT, so it is essential to use passthrough.

Why should you enable the VPN passthrough

VPN passthrough is mostly built-in, in the old routers. But if this feature is not allowed, this is not a big issue, but only if you are using an IPsec or PPTP protocol-based VPN. Sometimes, people ask you to open some ports to enable VPN passthrough.

Keep in mind that by opening the ports of a router, you cannot enable the VPN passthrough. All that you need to do is to complete the basic setup of the VPN. If you have been using PPTP, L2TP or IPsec protocol

Your VPN will work if you have VPN passthrough and IPSec, PPTP, or even L2TP VPN protocols.

VPN Passthrough Netgear

Netgear is a kind of router, and it claims that its routers allow the VPN passthrough for PPTP, IPsec, and L2TP VPN protocols by VPN passthrough.

There are different models of Netgear routers that support the feature of VPN passthrough. You can go for the model D6300 or DGN1000.  

How to Put on a VPN on your router

You can install a VPN on your router by following some necessary steps. The instructions for installing a VPN are also mentioned on the router. You may have to buy the pre-configured routers based on the VPN.

Before putting on the router, you should make sure that the internet is on and the router is connected to the internet. The router must also support that kind of VP protocol.  

The following are some necessary steps;

  1. Use the wifi or Ethernet cable to connect the router with your device.
  2. Find the setup Tab on the control panel of your router.
  3. Go to the “Connection Type” option.
  4. You will have to select the protocol of your VPN now.
  5. Username, password, and name of the VPN server are required for the next step.
  6. Save the settings.

Router Setup is completed, and you can use the VPN on your router.

Should I Disable the VPN passthrough

It is not safe for you to disable the VPN passthrough. It has both advantages and disadvantages.

The advantage is that it provides you better security because the ports of open communication become blocked. No one can now access these ports.

The disadvantage is that if someone from behind the firewall attempts to build a connection with your VPN, the connection will be blocked.

If you are the only user of a network, you should disable the VPN passthrough. But if your VPN is for a team or organization, you should not disable the VPN passthrough.
