Greetings, I am running Redhat 7.3 with Linux kernel 2.4.20 with H323 applied (compiled in the kernel). However, I am still not able to get netmeeting working over the NAT server. Is there any detailed documentation that I could refer to? Also, is there any way I could get MSN voice chat and file transfers to work over NAT firewall? I am running iptables-1.2.6a-2 on my NAT firewall. I have a rule in my firewall script that is SNAT-ting all the internal traffic to the IP address of the ethernet card connected to the Internet. Please assist. Thank you very much. Dhyanesh Ramaiya dhyanesh@intafrica.com
