Nighthawk rax70 proper ipv6 settings for Comcast

[Jefferyb64]

I'm having trouble finding out the proper settings for ipv6 with Comcast on nighthawk rax70. It's currently set to off. Comcast keeps telling me to contact my router manufacturer. Can anyone tell me what settings to use?

Try Auto or Pass thru.

Be sure the ISP provides native IPv6 support. Again they should have this information. Modes depends on what the ISP puts out. Not what the router can do. It depends on what the ISP configures IPv6 for there services.

When you make the changes @FURRYe38 suggests, a good place to test is here:  https://whatismyipaddress.com/ 

What is the brand name and model number of your upstream modem/gateway/ONT your RAX70 is connected to?

I'm on xfinity and auto detect has always worked fine for e.
