C6300 IPV6 firewall disabled by default

[Griffscavern]

Hi all,

I recently bought a c6300 cable modem/router. I am using it for my home network. My ISP is Comcast. The firmware is current.

My question is:

Why is the ipv6 firewall disabled by default? Should I enable it. I did at one point but kept getting No Ranging Response received - T3 messages (I'm not sure if I had enabled it before this happened, or if it was after). So many that my event log took forever to load. I actually had to log in a few times to clear the log (it was so big it would freeze my browser). I'm on my Android phone. No computer at this time in my home. So I'm stuck with using my phone to connect to my modem.

If anyone can give me an answer on this I would really appreciate it.

Thank you,
Griffscavern

Hello Griffscavern 

It shouldn't cause problems since your area may be still using ipv4

Hello Griddscavern

Are you having connection issues on the modem? and it could be disabled by default because of the ISP config file if they are not using IPV6 yet.

Hi DarrenM,

No, I'm not having any connection issues. I'm not sure if Comcast is using ipv6 in any way yet. I was just wondering if it being disabled is going to cause any issues.

Thank you DarrenM. You're probably correct. I'll just leave it disabled for now.
