Hi, I'm based in the UK and my ISP is Community fibre, as far as I'm aware my IPv6 IP address is dynamic.
WAN IPv6 configuration is as follows:
IPv6 Configuration Type: DCHPv6
DHCPv6 client configuration
Prefix delegation size: 48
Send IPv6 prefix hint: ☑︎
LAN IPv6 configuration is as follows:
Track IPv6 Interface
IPv6 Interface: WAN
IPv6 Prefix ID: 0
☑︎ Allow manual adjustment of DHCPv6 and Router Advertisements
I'm trying to create a Dynamic IPv6 Host Alias to use in a firewall rule, as I understand that if the prefix supplied by my ISP changes all my LAN IPs will change too.
I've checked out the documentation here https://docs.opnsense.org/manual/aliases.html#dynamic-ipv6-host (https://docs.opnsense.org/manual/aliases.html#dynamic-ipv6-host)
I'm a complete novice when it comes to IPv6, so apologies in advance. I understand that I need to "enter only the suffix of the address ... the lower 64 bits of the address" however my IP doesn't seem to match the format of the examples given:
E.g. Example IP: 2a02:1234:5678:0000:aaaa:bbbb:cccc:0001
The Dynamic IPv6 Host Alias for this would be: ::aaaa:bbbb:cccc:0001
My IP looks like: 2a02:XXXX:XXXX:0:230:XXXX:XXXX:XXXX
I've tried the following for the Dynamic IPv6 Host Alias, but my firewall rule doesn't work unless I enter the full IP :/
::230:XXXX:XXXX:XXXX
::0:230:XXXX:XXXX:XXXX
Any help appreciated!
Have you looked at ISPreview or ThinkBroadband, both have threads on Community Fibre?
Thanks, yep but I couldn't find anything in regards to Dynamic IPv6 Host aliases.
I saw a few references from a search of "Community Fibre"
One mentioned that a static IPv4 address impacts IPv6, another that talked about different IPv6 allocations after ~7 days and another thread about using 3rd party routers.
They may not be relevant today, but they may be useful.
