Folks
It appears that Comcast is using 6to4 tunnelling on all new installs in Washington and Oregon. I am trying to install Centos 6 (latest), and nothing I do seems to work.
My method is as follows:
The Comcast modem is directly connected to the box. Insert the NetInstall disk and bootstrap.
Select the URL method of install, and enable both IPV4 and IPV6. I know that if I enable IPV4 only, it fails.
Network manager never manages to initialize the network.
---------------
As a sanity test, I took a functioning Windows 7 laptop, plugged it into the Comcast Modem, and the connection came up and worked. I had both an IPV4 address (globally routable, likely dynamic) and an IPV6 address. I know therefore that the modem, and cable all work.
---------------
Is Linux installable on such a network? It installs elegantly and effortlessly in an IPV4 environment. It appears that there will be a growing number of 6to4 tunnel environments as the world slowly moves to an IPV6-only protocol.
Advice please?
