Comment 3 for bug 1491317

I've came across an environment with a shortage of ipv4 addresses, where port forwarding with fixed ips would really help. It seems from the spec that port forwarding on fixed ips in DVR is easier to implement than forwarding on floating ips (just like the SNAT part on the network node). Maybe this could be done first. I may be wrong, though.

I had no experience with DVR, but it seems from the Networking Guide[1] that port forwarding on floating ips have to be done in the relevant compute node.
