You are correct, it doesn't support H.245 tunnelling. However, it does work with gnomemeeting (at least for me). Documentation says: Author: Jozsef Kadlecsik <kadlec blackhole kfki hu> Status: Alpha This adds CONFIG_IP_NF_H323: H.323/netmeeting support module for netfilter connection tracking and NAT. H.323 uses/relies on the following data streams: Port Description 389 Internet Locator Server (TCP) 522 User Location Server (TCP) 1503 T.120 Protocol (TCP) 1720 H.323 (H.225 call setup, TCP) 1731 Audio call control (TCP) Dynamic H.245 call control (TCP) Dynamic RTCP/RTP streaming (UDP) The H.323 conntrack/NAT modules support the connection tracking/NATing of the data streams requested on the dynamic ports. The helpers use the search/replace hack from the ip_masq_h323.c module for the 2.2 kernel series. At the very minimum, H.323/netmeeting (video/audio) is functional by letting trough the 1720 port and loading these H.323 module(s). The H.323 conntrack/NAT modules do not support - H.245 tunnelling - H.225 RAS (gatekeepers)
