I have a cisco 2621XM with IOS 12.3.
Is there a command for the cisco router to NAT the connection address within the SDP packet?
Is there a command for setting a static NAT with a large port range for RTP? Right now I have to dedicate a whole public IP addy for RTP since I don't know how to do specify a range.
If I have the following scenario.
WAN Port
fa0/0
10.10.10.1
LAN Port
Fa0/1
192.168.1.1
VOIP Server(Interactive Intelligence, Handles all SIP messages)
IP 192.168.1.50
VOIP Media Server(Handles all RTP Traffic)
IP 192.168.1.100
Current NAT setup
ip nat inside source list NAT_Addys interface fa0/0 overload
---------NAT Overload for all my LAN devices
ip nat inside source udp 192.168.1.50 5060 fa0/0 5060
---------Static NAT for SIP messaging to my VOIP Server
ip nat inside source 192.168.1.100 10.10.10.2
---------Static NAT for RTP to my Media Server
ip access-list standard NAT_Addys
permint 192.168.1.0 0.0.0.255
