I added AllowAdd=true and Broadcast=true to the custom.conf file and
DisallowTCP=false to the security section. I also open ports 177,
6000-6005 and 7100 in the host's firewall (not the router's) and
restarted gdm but there was no change. 

If AllowAdd=true was being honored, there would have to be some way of
adding a host but there isn't. 

I also note the the gdm reference manual has not been updated since
2004.
