Hello, I tried following the instructions for symmetric NAT from the wiki. However, I still have the same problem. The wiki states: "Here are some rules you can use for GNU/Linux with iptables. It doesn't forward any port. Forwarding a few additional ports might be required for H.323, but not for SIP. " So I copied the text that follows into a text file called ekiga.sh, make it executable and run it. I get the following output: "Setting up IPtables rules ./ekiga.sh: 9: cannot create /proc/sys/net/ipv4/netfilter/ip_conntrack_udp_timeout: Directory nonexistent ./ekiga.sh: 10: cannot create /proc/sys/net/ipv4/netfilter/ip_conntrack_udp_timeout_stream: Directory nonexistent " Now what? What did I do wrong? Help?

Unfortunately, it does not work at all. I followed the vague (and somewhat misleading) instructions and am still not able to make phone calls. I am confused about the terminology used in the instructions as they seem to be geared towards people with a bit of experience in the underlying technology of Ekiga. I set up a PC-to-Phone account and Ekiga shows a successful connection to diamondcard. However, when I try to call (001303xxxxxxx), I see the message "Calling" and nothing ever happens. I understand this may have something to do with my router and thus tried to run the "iptable rules" provided in the FAQ and get this error: ./ekigash: 9: cannot create /proc/sys/net/ipv4/netfilter/ip_conntrack_udp_timeout: Directory nonexistent Furthermore, the FAQ states "Here are some rules you can use for GNU/Linux with iptables. It doesn't forward any port. Forwarding a few additional ports might be required for H.323, but not for SIP." What is this suggesting I do? How would I "use" these "rules"? On setup, Ekiga detected Symmetric NAT and went on to explain about concepts I do not currently understand, such as port forwarding. Can anyone explain this in less technical terms?
