Is there a cisco validated config for exposing a SX20 unit on a router? I have a 2911 router.
I don't have a firewall at the site.
I know I can nat the device and enable the following incoming ports the on public ip
udp 1719
tcp 1720
tcp 5555 6555
tcp 11000 20999
udp 2326 - 2845
Do i need to enable any inspect rules for outgoing traffic from the unit?
I know on the sx20 unit, i would have to set the NAT to auto and the call mode direct.

If you do a search for SX20 Standalone in these forums, you will find much information on the ports and requirements for using a SX20 behind a router.
For all video conferencing purposes, and H.323 and SIP packet inspection/fixup should be disabled on your router.

Hi,
Have you made this work?
Can you share the configuration of your router.
Thanks
