I opened an support ticket on getting IPv6 Virtual IP that will allow me to place a URL to internal IP address for web servers. 2.5.2021, Fortinet L2 engineer wrote up a NFR for my URL Virtual IP request for IPv6. FutureCon is looking into a IPv6 talk. I moved the Ubuntu DHCP and DHCPv6 back to the Fortinet because IA-NA and IA-PD need DHCPv6.
I have some interesting news to report. AT&T only presents one delegated prefix instead of 8 to 16 like Comcast. Fortinet found more IPv6 bugs. I hope they can get it resolved soon and get AT&T involved to help on their end. So I can use IPv6 on one interface of the 60E only unless I subnet it down.
