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.
