In the office we get the IPv6 address by dhcpv6 From this address, we have Internet connectivity, but this address is not available from anywhere, as if there is a stateful firewall somewhere in the middle.
Hello, @vpsh89! We appreciate you taking the time to reach out to us for help with your service connection. I see it has been a few days since you created this post and I wanted to check in to see if you were able to find a resolution or if you are still in need of assistance?
Double-check the firewall settings in the modem. At least for my modem, the IPv6 firewall was set to "Typical" by default, which blocks inbound connections. Select "Custom" and disable the firewall (your modem may be different)
