Hello, I have a linux gateway (SuSe 7.1/ kernel 2.4.2) with iptables as firewall and I want to use a voice over IP (H.323) tool like Netmeeting. All internal IPs are masqueraded. My problem is, that netmeting uses static and dynamic ports to comunicate. I don't know how to configure iptables. I have found some modules for dynamic NAT. But all these modules work only with ipchains and kernel 2.2.x. Are there also modules available for iptables? Or is there another possibility with iptables?
