We have a CISCO Catalyst 2900 Series Router in our headend lab(It's a cable company working on VOD solutions). We have addresses on an internal 191.254.84.X network (for our set top boxes) and these boxes are able to communicate with a router (cisco 2900) that lies in between the 191.254.84.X network and a 10.20.4.X network. What we would like to do is set up natting on the cisco catalyst router 2900 so that whenever it sees a 10.20.4.198 and 10.20.4.199 address to translate them into 192.168.210.11 and 192.168.210.9 respectively. Is this possible? I will read up the documentation on the CD as well as what is on your web site. Please assist. Thank You.
