My Zyxel router has one check box to enable/disable IPv6, I've seen no reason to enable it myself. I played around with it a couple of years ago but could only get a /64 address from my ISP. I wanted at least a 62 because I use three subnets and I want them completely isolated except for a router management port. Maybe it can be done witha /64 but I couldn't figure it out You do it exactly as you would with IPv4 - classless subnetting. That /64 can be subdivided into virtually whatever you want.
Let's say you are given 2001:db8:11:22
As you complete isolation, I presume physical networks, on your router with the four nics:
nic0 = 2001:db8:11:22::/64 nic1 = 2001:db8:11:22:a::/80 nic2 = 2001:db8:11:22:b::/80 nic3 = 2001:db8:11:22:c::/80
For instance, on my own network (at home), I use
2001:db8:4c68:1:ff99::/112 - known wifi clients 2001:db8:4c68:1:ff99:ffff::/112 - guest/unknown wifi clients
(not physical, just separate vlans).
Yes, I tried all of that Per. I just couldn't get it working with the Zyxel router that I had at the time. I remember documenting my saga on the OT list. It was one of those problems that had too many variables, so I just abandoned the effort. I don't see any clear reason to attack it again, except maybe for the challenge. IIRC dhcpv6 was part of the issue, not sure. Maybe James Knott can get me motivated again? Regards, Lew
