Can you tell me what this all means? I need to understand things like:
* Through what device do such services as email, tcp, http, udp and icpm
access my box, through which do they leave and which (if any) are used
for internal communication?
* Also would help, what is fxp0 *traditionally* used for?
Thanks,
beno
