Your mileage may vary. Most of the code that we write, assumes that
nodes are not behind a NAT and that both forward and reverse DNS

I don't know what these ports are.

You will at least need to open TCP port 22 for SSH access and TCP port
80 for web access to the PlanetFlow database. I don't know how you will
handle inbound ICMP; NATing the node will almost certainly break any
experiment that depends upon ICMP. We are discussing opening up Node
Manager to external access, but have not decided yet. More ports may
have to be opened eventually. So, for now, at least 22 and 80.

Software running on the node needs to contact both boot.planet-lab.org
and www.planet-lab.org via outboudn HTTP (80) and HTTPS (443). If your
NAT is filtering outbound traffic, turn this off.
