I have looked for a solution to this problem but everything that I have found never seems quite match this scenario.
I have a small colocation space and I only get 5 IPv4 addresses. I also get an IPv6 /64 block. I only have one LAN drop, external IP addresses only. The colo provider doesn't provide private network addresses.
The gear I have is a 4 node superserver... each node has IPMI NIC and 2 regular NICs. I also have space for a 1U "switch" of some description that I am seeking advice on what to get. My understanding is that the IPMI ports only support IPv4.
I need to be able to access these 4 IPv4 IPMI ports with only the "switch" operating.
I also need at least 1 IPv4 address per node for web servers etc so I am out of IPv4 space.
What I would like to do is find a 1U switch/router to route the IPv6 addresses to the IPv4 devices.
I have looked at some of the Layer 2 and Layer 3 switches and they have static routing, but I don't think it would route across protocols like this. Am I going to have to break down and put in a full router?
What are some of the approaches to achieve this functionality?
