UFW (Uncomplicated Firewall) with Wireguard connecting to Mullvad VPN sanity check on UFW setup.
(lemmy.world)
I would really appreciate it if someone would double check me. Sorry for the screenshot. Either the Lemmy code button isn't great or I'm just dum at formatting.
This has local *arr servers available and traceroute shows me going through the VPN.
The largest blue blotch is the ip address of a mullvad vpn server.
Rpi4, Raspberry Pi OS lite.
Mullvad VPN. IPv6 has been nuked. Using Wireguard through wg-quick.
wg2 originates from a .conf file from Mullvad with IPv6 stripped.
Do these UFW settings look right?
Pretty sure DNS is 53 UDP. Not sure if you meant it like that.
Port 53 TCP is for dns zone transfers
I've got 53 and 5353 open so that DNS will work for my local network when connecting to *arr and jellyfin.
I.E. type raspberrypi:8989 in a browser to bring up Sonarr.
Should I restrict to UDP?
No, you should keep both udp and tcp port 53 open going out. blocking dns vc/tcp will result in dns being partially broken.
