IPv6 Connectivity Issue - No Network Access

[dennis6101990leon]

Hello,   HealthCare gov

I've encountered an issue with IPv6 connectivity on our network, which is causing a No Network Access error. This problem is preventing devices from connecting to the internet using IPv6 addresses. 

I've restarted my devices and network equipment, also Inspected DNS configurations and firewall settings. 

I need help. Any help would be appreciated. 

Thanks in advance!

Which addresses are assigned to your device?

What does a traceroute result in?
