Last week I bought the new edition of O'Reilly's "Building Internet Firewalls". It mentions that Netmeeting uses the T.120 protocol (which will work with NAT) and the H-323 protocol, which will not work with NAT. H-323 needs a H-323 aware proxy. H-323 seems to have IP addresses embedded in the data portion of the packets. NAT only looks at the IP addresses in the headers. On page 535 the book gives this recommendation for Netmeeting : "Do not allow Netmeeting across your firewall." ===Janko van Roosmalen - Vught - Netherlands=== On Sat, 23 Sep 2000, Charles Peters - Tech Support wrote: > > Greetings: > > I currently have a FreeBSD gateway/router > providing internet access to my lan.
