IPv6 Neighbor Discovery (ND) Proxy, Oh My!

In a couple of blogs and I had mentioned ND-PROXY.

ND-PROXY is an IPv6 Neighbor Discover Proxy, it allows a router or a node to respond to IPv6 Neighbor Solicitations (NS) messages.

It does this on behalf of hosts located on another segment within the same sub-net or prefix.

It is useful for example if you have /64 prefix and want to put wireless clients on it but do not want to use an existing prefix or you ISP only gave you a /64 (the nerve!).

I will go over a configuration on a Linux server stitching a couple of IPv6 segments.

IPv6 Delegation, Follow Up, NDProxy, Oh My!

This is a follow up to my PfSense blog.

One thing that I mentioned in passing is that your ISP does not have to give you a global address on your WAN interface. Your LAN needs one if you want to access the Internet.

IPv6 Delegation, PfSense, Cisco, Oh My!

Hello there,

The topic of this blog may not be that relevant since IPv6 is being around now for many years.

However, I still see issues once in a while on forums, with IPv6 delegation and how to configure it on PfSense.

Since I can not control how my ISP delegates IPv6 to me, the next best thing is to lab the hell out of it.

Kea, DhcpV6, DDNS, Ubuntu 26, Oh My!

Hello there,

A while back, in a galaxy far away, I had a blog (and related posts) about using the ISC DHCP server.

That setup worked very well. However, the ISC DHCP server has been discontinued.

So it was time to try the Kea DHCP server.

It should be a standard setup, Kea is a modern replacement however, I run into a few quirks and it did not help that I was using the latest Ubuntu server version 26.

Open Nebula, VXLAN, EVPN Not, Oh My!

This is a follow up to my previous post.

On that post I did install an almost production Open Nebula cluster. The reason it is almost a production cluster, is because it has some pitfalls.

OpenNebula Cluster, ISO install, oh My!

In this blog I will show how to install an OpenNebula cluster from scratch, well almost, using an ISO that allows you to create a minimal configuration. The initial setup can be extended to have an almost functional production setup.

OpenNebula, Virtual Routers, VXLan, Oh my!

Hello There.

I did create a lab in which I was able to convert a minione server into a 3 node server, with the initial minione server acting as a controller. Eventually I will write how to do that.

This Blog instead is about the travails of configuring Open Nebula and the limitations of Sunstone the GUI. In particular trying to use VXLans and Virtual Routers.
