Replacing the CenturyLink provided ethernet router with OpenBSD

Unfortunately CenturyLink provisions their fiber to the home with a PPPoE authentication over vlan 201, this makes replacing the router more difficult than it should be. I also had to call CenturyLink support to get the password for the PPPoE connection.

cnmac0 is the egress interface on my EdgeRouter Lite.

Compilation

About

I faced bandwidth issues between a WG Peer and a WG server. Download bandwidth when downloading from WG Server to WG peer was reduced significantly and upload bandwidth was practically non existent.
I found a few reddit posts that said that we need to choose the right MTU. So I wrote a script to find an optimal MTU.
Ideally I would have liked to have run all possible MTU configurations for both WG Server and WG Peer but for simplicity I choose to fix the WG Server to the original 1420 MTU and tried all MTUs from 1280 to 1500 for the WG Peer.

Testing

On WG server, I started an iperf3 server
On WG peer, I wrote a script that does the following:
- wg-quick down wg0
Edit MTU in the /etc/wireguard/wg0.conf file

	Welcome to Jordan's grab-bag of common Binary Ninja Snippets.

	These snippest are meant to run with the Binary Ninja Snippets Plugin
	(http://github.com/Vector35/snippets) though they can all also be pasted
	directly into the python console or turned into stand-alone plugins if needed.

	To install the entire collection at once, just install the Snippets plugin via
	the plugin manager (CMD/CTL-SHIFT-M), confirm the Snippet Editor works
	(Tool/Snippets/Snippet Editor), and unzip this bundle (Download ZIP above) into
	your Snippets folder.
