6RD and Centurylink/Qwest Problem, need a helping hand.
-
My ISP is centurylink. I really would like to have a working IPV6 setup.
I am running 2 pfsense boxes in a CARP setup. Both boxes are running 2.2 RC.
Only one box is setup to do 6RD.
Wan setting are the following:- 6RD prefix 2602::/24
- 6RD Border Relay 205.171.2.64
- 6RD IPv4 Prefix length 0
Lan is set to track wan.
This IPV6 setup worked for a while, around November 20 when changes were made to 2.2 to fix 6rd. Now It does not work anymore. Since then I went through several pfsense upgrades and fresh reinstalls. I lost the ability to do 6rd around Nov 26. In the interim my dynamic IPv4 has changed as well. These are the 2 things that have changed in my setup since the time I had a working 6RD.
In the logs I see the following errors:

This was added automatically by 6RD configuration. I do not see additional pf rules on WAN
Am I the only one having trouble using 6RD on century link? If I am the only one, what am I doing wrong? Or is it a pfsense problem?
I have been battling this for the past several weeks without success.
Any help by anyone more knowledgeable on this topic would be greatly appreciated.Thanks
