Why do you need that much open?.
Iptables, with using statefull rules allows established/related ports to
be opened. Would not the other port(s) be related to the initial
contact port and thus fit these rules?
An example of what I mean is ftp. Control connection is on port 21, and
I do not need to list the data port as it is "related" so it is
automatically allowed. It seems netmeeting or gnomemeeting should work
similarly. I have not tried this but it seems logical.
