Having just replaced my virtualized OPNSense with a cheap eBay Check Point 4600 and loading up OPNSense, my public IPv4 and IPv6/56 all changed. This meant I had to go through the switches and a few other devices with static assignments (Proxmox) and resetting all the IPv6 addresses. This also gave me a bit of a headache until I realized I had to fix the routers in OPNsense too.
I want to use IPv6 ULAs to prevent these issues in the future. Global IPv6 assignment is still a must for internet access, but I want edge router to core router link via ULA and most devices on the network to have both global and ULA addresses.
How do I accomplish this with a Brocade ICX? Linux?
I'm still confused on the fc00/8, fd00/8, stuff. Can someone please dumb it down for me?
