What is VPN Passthrough & How it Works?

Virtual private networks or VPN’s as many of you know it allow for secure browsing and access to content on the internet that is normally restricted in your local region. So, most of you are here to know about what is VPN Passthrough?

They’re quite common nowadays and you may have even seen influencers having VPN companies sponsor their content, but do you actually know how you get access to them? One more thing is you need to have best router settings to access fast internet with VPN Passthrough.

Well, if that’s something you were wondering, you most probably have seen the term ‘VPN passthrough’ thrown around here and there. And that is exactly what we are here to explain today. Read on to find out more!

What is VPN Passthrough?

VPN passthrough allows your device, be it a phone or laptop, that are connected to the local area network of your router, make outbound VPN connections.

They do this because old VPN protocols such as PPTP and LT2P aren’t recognized by the NAT and in most cases just block the connection altogether.

In short, they allow data packets to pass from the user to the VPN servers so you may have secure browsing.

Working of VPN Passthrough:

Generally speaking, there exists a feature known as NAT or Network Address Translation that is integrated into routers.

These NAT’s enable the devices using the same network to use the same online connection and IP address but also cause some problems to using VPN’s with older protocols.

The problem lies in the information NAT’s receive, which in the case of the aforementioned protocols, is not sufficient enough for the NAT to verify it. And so, it blocks it instead.

And so, to get through this issue, VPN pass-throughs were implemented. They make a way for those older protocols to pass through NAT’s enabling VPN access.

You might have noticed that we mentioned the older protocols – they being the reason we need pass-throughs. Well if you have newer protocols such as OpenVPN or IKEv2/IPsec, then you won’t actually need one.

In fact, many of the wireless routers working built in recent years already have an integrated passthrough. So, it shouldn’t be a problem for you.
