What’s The Difference Between VPN & VPN Passthrough On A Router?
VPN feature on a router is the router that supports VPN technology natively, e.g., PPTP, L2TP or IPsec. You may configure this router to function as VPN server or set site-to-site VPN using other VPN gateway.
Here We Gonna discuss about
What Is The VPN Pass-Through Function On A Router?
What’s VPN Protocols of setting up a VPN (PPTP, L2TP, IPSec)?
In case a router has got VPN support what this means is that it supports VPN technology, e.g., L2TP, IPSec, and PPTP.
- Secure VPN – IPSec PPTP OpenVPN:
A VPN enables you to make a secure link between private networks via the internet. This actually gives you a chance to access your office or home network without necessarily being in your office or home.This has various benefits, mainly, you may access computers remotely on your network while located anywhere in the globe.This is very useful for organizations or companies that allow their workers to work remotely.
These VPNs also encrypt the data which travels between your network and computer making your private data extremely hard to intercept. Because of the said encryption, making use of the VPN is more secure as opposed to using typical unencrypted connection.
There are several protocols which you may use when configuring a VPN. These are L2TP/IPSec and PPTP. Let’s see some of their differences here below.
PPTP is an abbreviation for Point-to-Point Tunneling Protocol. This is a great VPN protocol which is supported by most gadgets and is simple to configure. It also features a low overhead meaning it can offer quick speeds.
Layer 2 Tunneling Protocol or L2TP is known to be a step up security wise if compared to PPTP. While PPTP only makes use of 128-bit encryption, L2PT utilizes 168-bit.
What is VPN Passthrough?
How Does VPN Passthrough Function?
Routers use what is known as Network Address Translation a.k.a NAT to allow all the gadgets on the network to share a single internet connection. This is much useful because it lets you connect multiple gadgets to the Internet.
Fundamentally, VPN Pass-through lets packets of data which originate from VPN clients on gadgets to pass via the router to VPN server, from home.
Why The Heck Is VPN Passthrough Required?
Almost all routers out there implement a function known as NAT to let various computers share similar internet connection; this is actually how your home router functions.
Both IPsec and PPTP VPNs don’t function with NAT natively. This is because a majority of routers implement NAT and this is a problem.
Fortunately, PPTP passthrough deals with this problem by replacing GRE which is the part of PPTP which does not function with NAT with enhanced GRE. The enhanced GRE functions well with NAT.
IPsec passthrough uses NAT-T encapsulating the IPsec packets in the UDP packet that functions with NAT.
How to Enable VPN Passthrough
- To sum up everything, despite their names being almost similar, both VPN passthrough and VPN features on wireless routers provide very different functions.
- In case you require to access your network while located anywhere in the globe, you achieve this by setting up a VPN. You must, therefore, purchase a router featuring VPN functionality.
- If you aren’t worried about this or you simply need to connect to a VPN, a router featuring VPN passthrough technology will work perfectly for you..
