It may have a setting for delegating an IPv6 prefix to your OpenWrt device. If enabled on the upstream router OpenWrt should be able to configure a global IPv6 prefix on LAN automatically. If the upstream router doesn't support prefix delegation then you can instead try the IPv6 relay configuration in OpenWrt as a workaround. 3
27.11.2021 · IPv6 configuration See also: Routing example: IPv6, IPv4/IPv6 transitioning The default firmware provides full IPv6 support with a DHCPv6 client (odhcp6c), an RA & DHCPv6 Server (odhcpd) and a IPv6 firewall (ip6tables). Also, the default installation of the web interface includes the package luci-proto-ipv6
2 dager siden · IPv6 working from WiFi, but not wired LAN. I am using OpenWrt 21.02.1 r16325-88151b8303 / LuCI openwrt-21.02 branch git-21.295.67054-13df80d on a BT Home Hub 5A. (I purchased this device through eBay with OpenWrt pre-installled). I used this to replace a Zyxel DSL Router. Previously, IPv6 was working fine, but with the switch to OpenWrt, ipv6 ...
On that setup LAN is getting the first /64 and WLAN is getting the 2nd /64. IPv6 from the LAN is working great while IPv6 from the WLAN does not work. I've tested this on Mac OS X and Linux and both are unable to get out over WLAN but are able over LAN (I've confirmed they're getting new IPs from the correct pool when I change devices).
25.11.2018 · To test the setup you’ll need either a VPS with IPV6 enabled or use online tools like this one. Once done with the firewall, IPv6 address of the router will be directly accessible from outside, but none of the computers on our internal network. On the other hand, all computers inside our network will be able to use IPv6 sites with no problems.
