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?
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?
Just did some reading as it has been many years since I did firewall… looks like dns is mostly UDP, but fails over to TCP if the dns reply exceeds 512bytes.
No, you should keep both udp and tcp port 53 open going out. blocking dns vc/tcp will result in dns being partially broken.
