What is a VPN Passthrough? What is IPsec Passthrough? Disadvantages All data packets that are passing through the router require encryption and decryption and putting a load on the CPU, which leads to increased computational time.

By enabling IPsec Passthrough, any vulnerabilities that exist at the IP layer in the remote network could be passed to the corporate network across the IPsec tunnel. Without IPsec Passthrough enabled, your traffic will be blocked if firewall restrictions are in place. This is not an issue if you have a modern router, but it can be an issue if you have an outdated router.

So far, it has been established that a VPN Passthrough is an important component to the process that allows VPN clients installed on your devices to work. It seems obvious that you need to get a VPN Passthrough, right? Well, the thing is, most modern routers already have a built-in VPN Passthrough. You just need to activate and connect to your VPN. If you find that you do need a VPN Passthrough, you need not worry too much since, again, most modern routers already have a VPN Passthrough that is pre-installed on it.

And usually, this is activated by default on most routers. However, there are times when you may need to activate your VPN Passthrough on your router manually. If you were successful in activating your VPN Passthrough, the system will prompt you to put in the username and password for your VPN.

If you are using legacy technology like outdated VPN protocols and devices running on ancient operating systems, then you will still need a VPN Passthrough. This will prevent you from encountering issues when you are trying to use your VPN.
