So quick question - preferably Y/N:

Were you able to connect RB5009 to Verizon FiOS and have working IPv6?
Were you able to connect S+RJ10 to Verizon FiOS and have working IPv6?
Were you able to connect RB5009 using S+RJ10 to Verizon FiOS and have working IPv6?

Hopefully someone will say 3 times yes.

I have problem with getting proper service. I tried almost all things and in the end I want to eliminate my equipment and put it on Verizon.

I tried using S+RJ10 on RB5009 and it didn't work.
I tried using connecting directly to RB5009 and it didn't work

I found that some ONT have issues with Intel NICs and with IPv6 TCP Checksum Offload as per here: https://www.intel.com/content/www/us/en ... llers.html but there is nothing I can do in MT about it. Just to check.

I know that there are some Android devices with same issue, hence my question if someone had similar setup working so I will know that this is problem with routing on Verizon side.

TIA

3 x Yes.

It was a routing issue with Verizon. IPv6 flies like a magic
