Re: [Business] Unexpected IPv6 address with Business Class stati

said by graysonf:

I am getting a /128 on WAN.

Also, when I use an online whatis my IPv6 tool, it reports my IP as the Temporary IPv6 Address that ipconfig shows:

Ethernet adapter Local Area Connection:

I don't see a Temporary IPv6 Address in your post. Do you not get one or did you not include it?

In my previous post, I was showing the ipconfig information for my Windows 2003 server which uses static IP assignment on its LAN interface, so no "Temporary" IPv6 address is present (also the ipconfig command in Windows Server 2003 and Windows XP does not explicitly identify the different IPv6 addresess; that has to be done using the netsh command). Shown below is the "netsh int ipv6 show addr" command for that server which does identify the different IPv6 addresses (but there is no "Temporary" address because static IP assignment is used).

Shown below is the ipconfig and netsh information from a Windows XP workstation (using DHCP) that does show multiple (unnamed) IPv6 addresses in the ipconfig results, and properly identified IPv6 addresses in the netsh results.

FWIW, I use "SLAAC + Stateless DHCPv6" for the LAN in my D-Link router because I have a mixture of static IP, Windows XP, and Windows Vista boxes connecting, and using "Stateful DHCPv6" would not work for me at this time. Someday, I may fully migrate into the 21st Century, but for now just getting IPv6 implemented is more than enough of a change.

What I posted was from a Win 7 box.

The only choice in my m0n0wall router that will work with Comcast IPv6 is to configure the LAN for DHCP-PD.

I also use DHCP-PD, but in my D-Link router that is a separate configuration option from "Stateful" and "Stateless".




If I select the "Stateful DHCPv6" option, my Windows XP and static IP boxes don't get native IPv6 addresses (the dual NIC server boxes do however revert to using Comcast's 6to4 tunnel).

If I needed static IPv6, I'd go back to my HE tunnel. Never had any problems with it.

For some reason my m0n0wall system log is being flooded with something to do with that DHCP-PD configuration:

Alright, I have this sorted. I disabled the generation of Temporary IPv6 Address generation.
