HOW TO ENABLE NETMEETING ON 1720

[1alonso]

Hi

I am new to cisco routers and know a bit of programming as standard configurations. I have configured my cisco 1720 to acces tha internet fine and have natted ports 1720, 1723 tcp and udp from aouside and inside and I can make netmeeting calls fine. The problem arrives when trying to have someone call me.
I get the ring at my pc but when I answer, the other PC keeps ringing and no connection is performed. I suppose is because the udp negotiation is not being performed but I just do not know how to doit... I have tried what I know bu I cannot go no further. I have replaced the 1720 with a normad broadband router like linksys to test my pcs and everything works fine woth them.. can make and receive calls.

Any help will be gratefully appreciated.

is your third nat statement a typo?
ip its being redirected to is 250 isntead of 150

 

[1alonso]

Yes... it is a typo... it is intended for 150...
