WSL 2 Cisco AnyConnect Networking Workaround

Overview

WSL 2 uses a Hyper-V Virtual Network adapter. Network connectivity works without any issue when a VPN is not in use. However when a Cisco AnyConnect VPN session is established Firewall Rules and Routes are added which breaks connectivity within the WSL 2 VM. This issue is tracked WSL/issues/4277

Below outline steps to automatically configure the Interface metric on VPN connect and update DNS settings (/etc/resolv.conf) on connect/disconnect.

Manual Configuration

Set Interface Metrics

58 bytes of CSS to look great nearly everywhere

When making this website, i wanted a simple, reasonable way to make it look good on most displays. Not counting any minimization techniques, the following 58 bytes worked well for me:

main {
  max-width: 38rem;
  padding: 2rem;
  margin: auto;
}

#!/bin/bash

systemctl stop rsyslog

# Cleanup (approximating the defaults of https://libguestfs.org/virt-sysprep.1.html#operations)

# Remove the crash data generated by ABRT
rm -rfv /var/spool/abrt/*

# Remove editor backup files from the guest

Description

This makes it easy to automate pausing your Cloudflare zone(s), renewing your letsencrypt certs, and then unpausing your zone(s).

Installation

• Ensure python-cloudflare is installed either in system or virtualenv.
• Make sure you chmod 0700 certbot-renew.sh before you add your credentials.
• Replace your existing certbot renew cron job with something like @daily /path/to/certbot-renew.sh.
• It's helpful to have MAILTO="youremail" in the top of your crontab to easily see the output whenever it runs.
