[22.1]

The links below might be helpful. ATT makes IPv6 difficult.

That setup has been working great for me with ATT Fiber + OPNSense 22.1.  Three public IPv6 addresses for three interfaces.

Came to the forum today wondering if this setup is still working for people in 22.7.   If anyone tries, please report here, thanks. 

Greetings, I'm trying to use my ISP's 6rd relay so that I can have a dual stack network at home and access the IPv6 internet.  I previously used the 6rd relay with openwrt successfully for over a year.  Really like opnsense, and hope I can get it to work with this software.   I'm using "OPNsense 16.1.17-amd64, FreeBSD 10.2-RELEASE-p18".

Charter Communications provides the following information for their 6rd border relay:

6RD Prefix= 2602:100::/32
Border Relay Address= 68.114.165.1
6RD Prefix Length= 32
IPv4 Mask Length= 0

(source: http://www.charter.net/support/internet/ipv6-faq/)

Notice that the prefix length is 32 bits.  However when I select the "6rd Tunnel" option for "IPv6 Configuration Type" on my WAN interface the 6rd options that appears only allow me to select a prefix length from 0 to 31 bits.

Anyway, after selecting 31 bits I do see this interface on the router:

wan_stf: flags=4001<UP,LINK2> metric 0 mtu 1280
   inet6 2602:100:8000:: prefixlen 63
   nd6 options=1<PERFORMNUD>
   v4net 97.88.xxx.xxx/31 -> tv4br 68.114.165.1


But I'm unable to ping any IPv6 addresses (from the router).  Tried IPv6 hostnames and literal ipv6 addresses to rule out dns problems.
