Is your LDM behind the firewall installed with the ~ldm/bin/rpc.ldmd
executable setuid root? That is needed for the LDM to run on port 388.
If you have not done this configuration, the LDM will have to be dynamically
assigned a port at runtime- which is one reason you would have to open port 111
and those above 1024.

On the machine behind the firewall, try running "rpcinfo -p" to see
what port program 300029 is running on. If it is not 388,
then you have not installed the rpc.ldmd setuid root.
