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?<br />

Long story short:<br />
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.<br />
Router is 1605 running IOS 12.2(31).<br />
<br />
Here is how I did the natting:<br />
ip nat inside source route-map test interface Ethernet0 overload<br />
ip nat inside source static tcp 10.X.X.X 1720 207.X.X.X 1720 extendable<br />
ip nat inside source static udp 10.X.X.X 1720 207.X.X.X 1720 1720 extendable<br />
ip nat inside source static tcp 10.X.X.X 1720 207.X.X.X 1720 1503 extendable<br />
ip nat inside source static udp 10.X.X.X 1720 207.X.X.X 1720 1503 extendable<br />
ip nat inside source static tcp 10.X.X.X 1720 207.X.X.X 1720 389 extendable<br />
ip nat inside source static udp 10.X.X.X 1720 207.X.X.X 1720 389 extendable<br />
<br />
Any ideas?

Netmeeting router configuration

Networking is the process of connecting computing devices, peripherals and terminals together through a system that uses wiring, cabling or radio waves that enable their users to communicate, share information and interact over distances. Often associated are issues regarding operating systems, hardware and equipment, cloud and virtual networking, protocols, architecture, storage and management.

Networking

Hardware-based firewalls provide more sophisticated protection for inbound and outbound traffic than the simple Windows software firewall or the basic NAT firewalls found in routers. These devices implement techniques such as stateful packet inspection, deep packet inspection, and content filtering; and may include built-in antivirus and anti-malware protection.

Hardware Firewalls

The Dynamic Host Configuration Protocol (DHCP) is an auto configuration protocol used on IP networks and an extension of the Bootstrap Protocol. DHCP allows for computers to be configured automatically to communicate with each other over an IP network without the need for manual setup by a network administrator. The implementation of DHCP relies on a DHCP server to hand out network configuration information to DHCP-capable clients that request an IP address (and other information required or useful in communicating with other devices on an IP network). In addition to an IP address, common configuration information served over DHCP includes a default gateway, subnet mask and DNS sever(s).
