Figured it out... Must manually set a the full IPv6 addresses in the DHCPv6 ranges. Cannot use the suffix only.

General Discussion / Static IPv6 address on LAN but can't use DHCP for clients
« on: July 16, 2024, 08:41:18 am »
Hello folks!
I have everything working great with track interface, RA/DHCPv6 working exactly how I want it.
However! I'd like to statically define my LAN address rather than have it assigned by DHCP. When I do this, DHCPv6 service stops, and I cannot get it to turn back on. IPv6 is routing no problem, because if I statically assign an address to a LAN client, I can ping the LAN interface IP I set and I can ping Google's IPv6 address.
Am I missing something simple?

24.1 Legacy Series / DS-Lite IPv6 Issues
« on: April 12, 2024, 08:16:36 am »
Hi all, pretty new to all of this so excuse any presumptions or lack of knowledge on my end. I did a bunch of digging around the forums and I've got my DS-Lite almost working. I'm successfully connected by IPv4! But I'm having issues with IPv6 connectivity. Seems no matter how I configure my WAN/LAN interfaces I cannot get my LAN hosts any IPv6 connectivity. However! I can ping public v6 addresses from my WAN interface successfully.
This is my current setup~
WAN: No IPv4. IPv6=SLAAC. In Interfaces > Overview I get a /64 public v6 address and LL address, gateway shows a different LL which I assume is upstream/ISP. Routes show default, DNS addresses, AFTR address, public /64 delegated prefix, and LL (fe80::%re1/64).
LAN: Static IPv4. IPv6=Track WAN, RA OFF (this is the only way I am able to get public v6 addresses on the LAN interface and LAN connected devices). In Interfaces > Overview I get a /64 public v6 address from same subnet as WAN and LL address, gateway is the same LL address assigned to LAN interface (weird?), only 2 routes to IPv4 subnet and fe80::%re0/64.
With the config above, I get public v6 addresses on my devices (including a temporary v6 address).
Within LAN, I can ping the public v6 addresses between hosts. I can ping the LL address of the LAN interface. I CANNOT ping the public v6 address of the LAN interface from a host. I can't ping LL of LAN to WAN nor from WAN to LAN (error bind: can't assign requested address). I can ping ipv6.google.com from LAN public v6 address but it has a ~40% packet loss.
If I had to guess, there's a routing issue between my LAN and WAN interfaces for IPv6. I get the same public v6 /64 address on my WAN interface if I set it to DHCPv6 and I can still ping ipv6.google.com, but I get no v6 address on the LAN interface nor on my devices no matter how I set my LAN interface.
Any suggestions are welcome!
