IPv6 with Prefix Delegation on Fortigate

[Edit 2018-10-18] Make sure to use FortiOS 6.0.3 or later for this, as earlier versions of 6.0.x will force your interface to IPv6 “static” when you make any change to the interface from the GUI, including changes to its IPv4 configuration, such as a DHCP reservation. I have not tested 5.6.x but am assuming it […]

[Update 2010-02-26] I just received an email from Comcast. They’ll start ramping up 6RD trials nationwide. Dual-stack trials will be regionally limited. […]

ipv6 addressing – there is no NAT, and “renumbering needs work”

Addressing is a big deal with ipv6. For people coming from ipv4, wrapping one’s head around ipv6 addressing can be hard. This post is a response to the comments discussion in the Standalone Sysadmin blog post urging uptake of ipv6. In the comments, we see people concerned with the fact that ipv6 addressing gives a […]

ipv6 at home, Part 2: Tunnel brokers, Windows “AYIYA” tunnel

Has it been 2 months? High time to get on with the planned ipv6 series, then. If you are entirely new to ipv6, it may pay to read part 1: overview. In this installation, I will cover the use of the SixXS tunnel broker to create an ipv6-over-ipv4 tunnel from your Windows PC, on XP […]
