Wireguard is one of the hottest new VPN’s available today, and is rapidly being adopted as the possible successor to OpenVPN. The Ubiquiti EdgeRouter is an awesome, high-performing wired router, which also comes with a firewall and vpn functionality. This article will walk you through how to quickly setup wireguard on an EdgeRouter 4.
Since my most recent article was about creating an OpenBSD L2TP-IPSec VPN, this article was warranted. This post is simply how to configure an OpenBSD client to connect to a L2TP-IPSec VPN.
Today I will be going over how to bring up a L2TP+IPSec VPN on OpenBSD. I am doing this because while I have been operating my own WireGuard VPN servers for the past few months now, I have experienced issues when the WireGuard server initiates over 100 connections. I know WireGuard is obviously still beta software, and that the issues could be caused by multiple things, but I wanted to give another option a shot.
Earlier this week, I was casually discussing various VPN’s with my colleagues. I’ve tried my hand at OpenVPN a couple times in my life, but was turned off by the complicated setup, poor iOS compatibility (at the time), and slow reconnection speeds. The conversation quickly came to revolve around a relative newcomer to the VPN world: wireguard. With the promise of ease of use, minimalistic code base, proven security, wireguard threatens to take the VPN world by storm.
