Hello,
I have a 4G Wan Service which is IPv6 enabled. I get an IPv6 address and it
will populate the route table automatically, though I am unable to connect to
sites using IPv6, "test-ipv6.com" will say I have no IPv6 address. Also, I
cannot ping the IPv6 default gateway address or any IPv6 sites, e.g.
google.com. I am using “ping6”.
I know the 4G connection is working as I can connect my MacBook directly to the
4G Modem (configured in Bridge Mode) and my MacBook gets an IPv6 address and I
a have working Internet connection with no issues.
I have provided some information below regarding my setup. I am using openbsd
6.8 (release) with latest patches installed. Any hints will be appreciated.
