SLAAC works entirely within the LAN, while online tests usually talk about ICMPv6 messages coming from the WAN. The recommendation is to unblock the latter, and that's because ICMP is usually overblocked – admins whack it away and forget to allow the useful bits. | |

| Sep 5, 2019 at 17:53 | comment | added | hiigaran | Right, so with SLAAC, I've noticed that online IPv6 tests mention I need to reconfigure my firewall to disable ICMPv6 message filtering. Any idea what I'd need to look for in my settings? | |

| Sep 5, 2019 at 17:48 | comment | added | harrymc | It's potentially both. The router may receive different IPv6 prefixes from the ISP and may append its variable part. There are many algorithms and configurations possible, but this is how it works in general. There exist also static IPv6 addresses, same as in IPv4. | |
| Sep 5, 2019 at 17:44 | comment | added | hiigaran | So it's the router that makes the addresses dynamic, rather than the ISP? I assume that would have to be disabled, if you were to run a server, correct? Or would you still also need to change your ISP plan/options to make it possible to run a public server? | |
