Other peer nodes are discovered from gnutella messages but you will always need a starting point to enter gnutella network, - that's why there's a number of GWebCaches (simple php/asp scripts that can be run on any web server).

If you cannot connect to any of those GWebCaches and if you can't run any locally (and if you don't have any static gnutella host) connecting to Gnutella will not be easy.

You could try multicasting pings to find other hosts if all gnutella hosts are on the same LAN.
