Does 6in4 work on the Netgear Cable modem?

Hi,

 

The Technicolor CGA4131COM, for whatever reason, is blocking IPv4 6in4 traffic (proto 41) even with the firewall completely disabled.  A Comcast tech is suggesting replacing it with a Netgear cable modem, presumably the CG3000DCR (not positive about this).

Does anyone know if this Netgear modem has issues passing 6in4 traffic for IPv6 tunnels?

I'm able to answer my own question.  Today they came by and took back the Technicolor modem and replaced it with this Netgear.  My 6in4 tunnel started working again!
