alt Hacker NewsI get an IPv6 address from my ISP (a /56 I believe), but I wish there was some good information on how to update my OpenWRT VLAN configuration, routing, and firewall rules to be able to support native IPv6 on my devices. Would love to be able to have direct IPv6 connections to the internet from my devices, but I want to make sure I can do it safely.

You only need to set nothing and it should setup ipv6 on all downstream vlan interfaces. For static prefix I'd you can set ip6hint per vlan interface. For each vlan interface you need a stanza in the DHCP config file. And regarding firewall, as with the default lan zone you might need to add new zones with the vlan interfaces and configure forwarding rules. That's it.
This was surprisingly complicated for me on Altice/Optimum, which is why my home didn't have IPv6 for a while even after they started provisioning.
We actually have a /128 address only, and had to tweak several settings including enabling IPv6 masquerading (NAT).
I haven't the slightest clue why they didn't give us a block.
