hello expert:
Very thanks and hope I can get your help.
I Use FreeBSD 13.0, and want to set it up as my home router. ipv4 is all
well running. The problem is about the ipv6 part.
Now, I can get the ipv6 prefix from my isp, the external interface and
internal interface of the router can autoconf ipv6 address, the router can
access the ipv6 internet.
But the client behind the router(freebsd) can not assign an ipv6 address.
Here is my configuration, It's great if you can give your comments about my
configuration. I hope it's enough. Thanks very much.
igb0 is the external interface
igb2 is the internal interface.
