Ipv6 | 1st time setup

[lleachii]

@Chatmandu

The new ipv6 WAN interface has received three ipv6 addresses via DHCP.

• /128
• /64
• /48

To be clear, that's not entirely accurate:

• The /48 is a Prefix Delegation issued, so that you can assign subnets to other interfaces, etc.

@Chatmandu

The /128 address can be pinged by some servers, but not others. Is this normal?

• You'd have to ask the company that provided the tool
• Did you edit IPv6 Ping on your firewall?

@Chatmandu

Where do I go from here? I presume I will need to configure an ipv6 DHCP server on my LAN interface, but the LAN currently has two ipv6 addresses configured.

• It appears you configured it - did you change anything from defaults?
• By default, OpenWrt should issue IPv6 addresses on LAN with an established wan6 connection

@Chatmandu

If I enable ipv6 DHCP on the LAN interface, will 'everything' happen automatically - e.g. will my local devices receive internet routable addresses?

Yes, it should have happened by default.

@Chatmandu

My VLANs are using static ipv4 addresses, so I guess I'll have to assign static ipv6 addresses.

No, you do not.

@Chatmandu

Will devices default to ipv4 or ipv6? Can OpenWrt be configured to use ipv6 with fall-back to ipv4 as and when required?

• That depends on the device and the software
• OpenWrt should now be accessible by it's IPv4 address too
• Here's 2 sites I'm aware will mention certain lookups are prefering v4 or v6

@Chatmandu

Am I going about this in completely the wrong way?

Seems you did pretty good - not really sure why the default wan6 interface was missing from your device, though.
