Hi all, is it possible to specify a range of ports to be NAT'ed on a Cisco 877 router? e.g If you have a VoIP setup and you want to forward 50 RTP ports, can you do this with one IOS commnad?
Thank you.

No, you cannot specify a range.
That is rarely necessary, because the router is smart enough to dynamically create NAt translations based on the signaling, SIP or otherwhise.

Are you sure it is not possible?
This forum post that I found this morning seems to say it is:
I will give it a try and see if it works.

You may be very well right, sorry for saying otherwise.
Still, you shouldn't need any explicit statement like that due to SIP-ALG feature in IOS.
