IPv6 connectivity on router is fine, No clients can connect to IPv6 at all.

[MrDosTheBoi]

Hello there! How are you today?

I've recently downloaded OPNSense a few days ago and I have tried to get IPv6 to work on my clients. I did "ping -6 google.com" on the OPNSense box. This works as expected. However, doing this on any client I have results in "ping: connect: Network is unreachable". Doing "ip -6 address" on a client shows that nothing is given by the router. My configuration for IPv6 is on the default when you install it. I've tried to put manual configurations of DHCPv6 and Auto discovery and still no luck.

Can someone please help me with my situation? Thanks you for your time and have a nice day.

It's always best to do an internet search for the solution to questions such as yours and there's always the OPNsense documentation.

Take a look at this article: https://homenetworkguy.com/how-to/configure-ipv6-opnsense-with-isp-such-as-comcast-xfinity/

An internet search for the following terms will get you all the information you need:

Hey Bill!

I have tried following many tutorials and the one you have sent me and they do not work. I've recently transitioned from x86 OpenWRT and it worked fine on there. I'm not sure what I am doing wrong.

Although far from a full-blown tutorial, I managed to get this to work earlier this week. These are the steps I took:

Hey everyone!

I just got IPv6 connectivity to work. I did not realize you had to enable link-local addresses manually on a bridge. Thought that would just be something always on. With link-local addresses on, I now have IPv6 working on my clients.

Thank you guys!
