I don't think dyanmic IP is the issue.   It's generally NAT (where a
node's local address is not usable to connect to it) or firewalls.

On the nodes that are not showing connection to the other nodes, try

telnet ipaddr port

using info from the welcome page.  If that connection fails, then it
indicates  network-layer issues.

If you are afflicted by NAT, as many are, then you need to set up static
ports for the storage node and a permanent reverse NAT translation on
your NAT box, and then put the global address/port in tub.location.

Or perhaps SOCKS or uPNP could be used to do this automatically.

Or you can finish IPv6 support and switch to that :-)
