IPv6 connections routed to IPv4 device

friedkiwi asked:

I have an IBM 9406-250 with V5R1 and IPv4 only connectivity, and want it to be reachable over IPv6. I cannnot install an IPv6 stack on it, but I want it to be accessible by IPv6 so I can drop the requirement to VPN to my home network.

I have an OpenWRT device running, which takes care of the IPv6 routing on my network and the tunnel to SIXXS, and I was wondering if it is possible to assign another IPv6 address to that device, and route it to the IPv4 IBM computer.

Which software do I need for this, and how is this technique called?

Edit:

One port would be sufficient actually, would it be possible to add an extra IP to the interface of the OpenWRT box, and redirect port 23 from the AS/400 to port 23 on the IPv6 IP?

My answer:


IPv6 support is available as of V5R2. If you can update, that might be an easy solution.

Another option is to place the beast behind a NAT64/DNS64 gateway. You may need a different device, as the last time I looked, NAT64 was not well supported on OpenWrt.
