MySQL Cluster Node Connections
That is weird. Two things I would check that can cause problems (in my experience):

1> make sure iptables is not running

2> make sure selinux is disabled (or permissive)

...at least in the beginning.

You can also try watching the network to see if things are going as suggested although I've never done this for mysql cluster specifically:

tcpdump -s0 -A -i any port 63132

Finally,

I noticed you forced a port number in the ndb mgmt config but not in the node configs. Is that going to be required info on the nodes? Try commenting that out in the mgmt node.
