Title: Delegated IPv6 to LAN Interface IP
Post by: Ryushin on December 19, 2024, 01:18:10 AM
I have delegated IPv6 working from my WAN to my LAN.  The WAN receives a /56 delegated range.  The LAN interface is configured to Track the WAN interface to get it's delegated IPv6 /64 range.  Everything seems mostly happy.  My only issue is that I can't seem to figure out a way to manually assign suffix IP of the LAN interface. For example, my prefix is 2605:1111:2222:a300 and my suffix IP is: ::aab8:e0ff:fe01:e172 so the IP address for the LAN interface would be: 2605:1111:2222:a300:aab8:e0ff:fe01:e172.  I want to manually assign the suffix so it will be something like this: 2605:1111:2222:a300::1.

I've been going down a rabbit hole for hours trying to solve this.  Any ideas on what I'm missing?

Set the "Optional Interface ID" (under "Track IPv6 Interface" in the Interface settings) to 1.

Perfect, thank you.
