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 think I’m just ignorant 😅 I know how ipv4 works and all the addressing and that’s why I’m currently sticking to it I just couldn’t really wrap my head about ipv6 I guess there aren’t any major changes just other addressed
There are definitely differences, but usually they don’t matter from a simple address and routing perspective.
For example, there is no ARP in IPv6. Instead another protocol is used called Neighbor Discovery Protocol, which actually is done through ICMPv6. Therefore, if you blindly block all ICMPv6, your network may break.
Once you have a grasp on v6, it is much better than v4 because even the smallest common v6 network size of /64 is many times larger than all the addresses in v4. Every device can have it’s own global ip, so you no longer need nat at all. Everything can easily connect, assuming there is no firewall blocking it.
