Re: Comcast Business IPv6 issues

[Justin Wilson - MTIN <lists () mtin net>]

I don’t think they have a clear policy for V6.  I can tell everytime my Comcast cable modem is updated because I lose 
all ipv6 connectivity.  Right now I am in one of those periods.  I can’t get ipv6 to pass the modem.  Customer support 
tells me it’s not an issue and must be on my end.  My he.net tunnels won’t even work.
