Greetings and Happy New Year to All,
I am experiencing a unusual problem. At least for me. I had ip 6 access when I first set up ip 6 on my home network. Recently, I think they changed my subnet and messed it all up or I did after the fact. I don't have ip6 connectivity for my host pve. I have an lxc container and vm that I have given global ip6s' to and they work fine. They ping the router (Verizon G3100) and I can find neighbors. The issue is from the code displayed below, that my pve host shares the mac address of the router or vice a versa. I am not real experienced with Proxmox and I have been exploring it for my work. I downloaded this utility recommended on r/ipV6 subreddit If you don't want to read the postings and running it displayed the text I have included below:
Ip -6 addr show does not display anything out of the ordinary:
Route does not look wrong:
localhost:
Pinging my hosts ip from its shell:
Any neighbors:
So I have been searching reddit, google w/o success. Perhaps my queries are not accurately describing the problem. l look forward to some feedback. If you go this far,
TY and Happy New Year.
