Thanks! I will test it out tonight and let you know how it goes tomorrow morning.

If this works I'll add this to my knowledgebase... I've had this same problem myself in the past ;-)

Yes, that will work - it's called &quot;Policy NAT&quot; - basically where you use an Access-List to create a &quot;policy&quot; and then apply it to a NAT statement.<br />
Let me know if you need any more help! <br />
Cheers! :-)<br />

Im trying to configure a block of ports to be NAT'd to a machine on the internal network. Its for our new VoIP system. Ports 10000-10500 need to be open and I dont want to have to write this for every single port:<br />
<br />
ip nat inside source static udp 192.168.43.230 10000 interface FastEthernet0 10000<br />
<br />
Is there a form of this command that will allow to specify the entire range of ports to be NAT'd?

Configure multiple ports for NAT in one command?

IP telephony (Internet Protocol telephony) is a general term for the technologies that use the Internet Protocol's packet-switched connections to exchange voice, fax, and other forms of information that have traditionally been carried over the dedicated circuit-switched connections of the public switched telephone network (PSTN). Using the Internet, calls travel as packets of data on shared lines, avoiding the tolls of the PSTN. The challenge in IP telephony is to deliver the voice, fax, or video packets in a dependable flow to the user.

IP Telephony

Voice over IP (VoIP) is a methodology and group of technologies for the delivery of voice communications and multimedia sessions over Internet Protocol (IP) networks, such as the Internet. Other terms commonly associated with VoIP are IP telephony, Internet telephony, broadband telephony, and broadband phone service. The term specifically refers to the provisioning of communications services (voice, fax, SMS, voice-messaging) over the public Internet, rather than via the public switched telephone network (PSTN).  Examples of the VoIP protocols are H.323, Media Gateway Control Protocol (MGCP), Session Initiation Protocol (SIP), H.248 (also known as Media Gateway Control (Megaco)), Real-time Transport Protocol (RTP), Real-time Transport Control Protocol (RTCP), Secure Real-time Transport Protocol (SRTP), Session Description Protocol (SDP), and Inter-Asterisk eXchange (IAX).

Voice Over IP

A router is a networking device that forwards data packets between computer networks. Routers perform the "traffic directing" functions on the Internet. The most familiar type of routers are home and small office cable or DSL routers that simply pass data, such as web pages, email, IM, and videos between computers and the Internet. More sophisticated routers, such as enterprise routers, connect large business or ISP networks up to the powerful core routers that forward data at high speed along the optical fiber lines of the Internet backbone. Though routers are typically dedicated hardware devices, use of software-based routers has grown increasingly common.
