Dynamic patch WSL2 to listen port on any interfaces. After some deep investigations into why ipv6 doesn't work (at least for me, ping ipv6.google.com doesn't work which causes connections to be incredibly slow since it tries the ipv6 address before the ipv4 address) despite having a global address. the distros standard set of networking daemons, which on a bridged adapter, can do everything they could do under native Linux. This can be solved by asking wsl not to create /etc/resolv.conf by appending the following to /etc/wsl.conf (create the file if it doesn't exist): Then restart wsl by restarting the LxssManager windows services.

I've managed to get around some networking and systemd issues by creating a network bridge with my Wi-Fi adapter and the WSL network adapter and genie along with setting a static IP to WSL, adding Cloudflare DNS servers to /etc/resolv.conf, and setting generateResolvConf = false in /etc/wsl.conf. , on the other hand, lets you turn off WSLs own address assignment. Pinging WAN IPs was now possible, but no DNS resolution. New comments cannot be posted and votes cannot be cast.
