6rd is setup & working - How to view DHCPv6 addressing & status?
I have 6rd setup & running on a Charter cable connection. It's working great…I configured the WAN interface option "IPv6 Configuration Type" to "6rd Tunnel" & configured the "6RD Rapid Deployment" section at appeared per the Charter ipv6 page. I set the LAN to "Track Interface" and just like that, ipv6 was working.
What I don't understand is how the computers on the "inside" are getting ipv6 addresses. If I go to the DHCPv6 page I get the red banner that says "The DHCPv6 Server can only be enabled on interfaces configured with static IP addresses." but if I look at /var/log/dhcpd.log I can see that the DHCP server is handing out ipv6 addresses.
Is this the expected behavior or should I be able to view & configure the DHCPv6 server?
If your LAN is automatically configured we setup both router advertisements and DHCP6 for the LAN so everything just works.
We don't have support for manually overriding this sort of configuration.
If your WAN address never changes you can statically configure the LAN address and then it all comes available to configure manually.
Thank you for the clarification.
I have 2 more questions then.
I should give the (now) static internal LAN interface static a /128 mask, correct?
After a while my clients seem to stop getting\renewing DHCPv6 addresses. If I do an ipconfig on the windows clients, for example, I can see that they only have their "fe80" link local addresses. I have to disable the interface and re-enable it to renew the DHCPv6 address. Any idea how to fix this? This did not happen with my HE.net tunnel….maybe it related to the ipv6 address tracking?
a lan is always a /64.
If you don't see any addresses you need to check if radvd is still running.
