Thanks for the replay... will save me from looking for workarounds/hacks to get around it. I'm just waiting to hear back from WOW_Dan or someone else on here about whether or not Arris will charge me to fix the TWC -> WOW IPv6 issue with my Motorola SB6141, and if so, how much, to see if it's worth it to send it back to Arris since my SB6141 is out of warranty.
