Long story short:
Have a cisco 1605, need netmeeting machine NAT-ed to a public address to allow outside callers in. NAT is done but Netmeeting still don't work from outside.
Router is 1605 running IOS 12.2(31).

Here is how I did the natting:
ip nat inside source route-map test interface Ethernet0 overload
ip nat inside source static tcp 10.X.X.X 1720 207.X.X.X 1720 extendable
ip nat inside source static udp 10.X.X.X 1720 207.X.X.X 1720 1720 extendable
ip nat inside source static tcp 10.X.X.X 1720 207.X.X.X 1720 1503 extendable
ip nat inside source static udp 10.X.X.X 1720 207.X.X.X 1720 1503 extendable
ip nat inside source static tcp 10.X.X.X 1720 207.X.X.X 1720 389 extendable
ip nat inside source static udp 10.X.X.X 1720 207.X.X.X 1720 389 extendable

Any ideas?

First off, you have to be running the correct IOS.  You need at least 12.15.t.  

You have everything running from port 1720.  You need to open each individual port from your firewall.  So it should read

ip nat inside source route-map test interface Ethernet0 overload
ip nat inside source static tcp 10.X.X.X 1720 207.X.X.X 1720 1720 extendable
ip nat inside source static tcp 10.X.X.X 1503 207.X.X.X 1503 1503 extendable
ip nat inside source static tcp 10.X.X.X 389 207.X.X.X 389 389 extendable
ip nat inside source static tcp 10.X.X.X 1731 207.X.X.X 1731 1731 extendable
ip nat inside source static tcp 10.X.X.X 522 207.X.X.X 522 522 extendable
ip nat inside source static tcp 10.X.X.X 1024 207.X.X.X 1024 extendable

I only need the instant messaging portion of netmeeting so will only be using ports 1720 and 1503. No voice or video used. I have this setup on a different site with a firewall only for those 2 ports. If that is all I am doing do I still need to upgrade IOS?
