                Workaround for WSL2 network broken on VPN
              
          
    Overview

Internet connection and DNS routing are broken from WSL2 instances, when some VPNs are active.
The root cause seems to be that WSL2 and the VPN use the same IP address block, and the VPN routing clobbers WSL2's network routing.
This problem is tracked in multiple microsoft/WSL issues including, but not limited to:

microsoft/WSL#5068
microsoft/WSL#4277


## setup-bridge.sh
#!/bin/bash -e

IFADDR="192.168.3.1/24"

if [[ ! ip link show docker0 ]]; then
  ip link add docker0 type bridge
  ip addr add "$IFADDR" dev docker0
  ip link set docker0 up
  iptables -t nat -A POSTROUTING -s "$IFADDR" ! -d "$IFADDR" -j MASQUERADE
fi
	#!/bin/bash -e
