I am sure this will be an easy question for some of you to answer, but I am new to configuring Cisco hardware using the CLI and would like to get this done efficiently - while learning a little about how to enhance/maintain my configuration as I go. This is why I have maxed out the points on this question.
I have a 3620 that I purchased for use in a colocation environment. I have to arrange with the colocation company when I want to go in and install new hardware - so I want to have as much of the configuration done as possible before hand - so I am not fighting with console commands while at the colo facility.
The 3620 has two ethernet ports 0/0 and 0/1.
I have a range of external IP addresses (lets say they are 220.127.116.11 through 18.104.22.168) that I want to assign to 0/0.
Depending on which external (incoming) IP and port, I want to route to an internal address & port.
22.214.171.124:80 (port 80) goes to 192.168.0.10:80 (webserver)
126.96.36.199:21 --> 192.168.0.50:21 (ftp)
188.8.131.52.3389 --> 192.168.0.51:3389 (remote desktop)
Since this is in a COLO facility - a couple things go without saying, but I will mention anyways:
All machines "behind" this router are servers, and will have static internal IP addresses. So DHCP is not required.
Based on what I have read, I will want to configure ethernet 0/1 as 192.168.0.1 and that is the interface connected to the my Switch (cisco 2924xl en) and then to all the servers.
Thanks in advance for your help.
