I can ping and telnet to the Internet with Cygnus (gateway) both with
name and number format. I _cannot_ ping in any way with Nebula (client).

Yes from Cygnus, no from Nebula.

The nameservers at my ISP do not respond to pinging, but other machines
that I know the _name_ of do respond and their numbers are resolved.
i.e.:
