Feature request: Add 6rd option under IP Assignment on physical interface settings for DHCP WAN connections

Hello.

I've read the 2-year old threads on how to configure 6rd but they assume static IP assignments on the v6 side at least. This does not work on dynamic IP address WAN connections. It would be great if the XG firmware could support this situation with 6rd.

The physical interface IPv6 settings would need to add a third IP Assignment option for 6rd that then asked for the 6rd prefix, prefix length, IPv4 CE mask length and IPv4 border router address. Then it could establish the 6rd connection and obtain an IPv6 WAN address just like it does now with DHCP v6. (Then the rest of the LAN configuration (RAs, etc.) would work the sameas with a DHCP v6 WAN connection.)

Here's an example with screen shots of how CenturyLink router is configured for 6rd on their network: www.centurylink.com/.../ipv6-turn-on.html

Another way to solve this would be to add an "WAN interface IP" option for Local Endpoint under the IP Tunnel configuration instead of requiring a static IPv4 address. (So the XG would automatically update this Local Endpoint value whenever its WAN interface IPv4 address changed.)

Hi Pegasus,

Is this in anyway related to DHCP-PD which is used primarily for stateless IPv6 connections?

If so, this feature is due in v18.

6rd is not on the roadmap. 6TO4 tunnels might help.

We are preferring instead to support DHCP-PD to provide Native IPv6 and the scale this provides.

Best,

Stuart

I don't think so. 6rd is used by ISPs who still have an IPv4 infrastructure. It's essentially a special case of a 6to4 tunnel. My main problem is that the current XG configuration assumes a static IPv4 gateway address so it doesn't work for DHCP WAN connections, precluding using IPv6 on such ISPs.
