This is my first time interfacing with a Cisco product. I found configuring the router with Config Maker v2.6 was extremely easy. However, I am having a terrible time understanding how to make NAT work in the following way:
Router's Public IP is x.x.252.90/24
Usable Public IP addresses are x.x.246.129-142/28
Router's private IP address is x.x.246.129/28
(However, I have not assigned this private IP address, instead I have assigned 192.168.1.254 as my Eth0 address)
I have configuree NAT for all users on the private network 192.168.1 on Eth0. I cannot translate external IP addresses to access my Web server, Exchange Server, and FTP server on the 192.168.1 subnet. External tracert's to my public IP's assigned to internal IP's all die at my router.
Throwing the configuration GUI aside, Could I ask for assistance with exact command lines needed to create the necessary STATIC NAT configuration for translating x.x.246.130:80 to 192.168.1.2 and x.x.246.131:25 to 192.168.1.1, and still have DYNAMIC NAT translations for all 30 users.
One more thing, Would it be more advantageous to install an Ethernet WIC card (which I do have)and route all x.x.246.0 traffic through Eth1 interface, and assign the public IP addreses to a second nic card on my servers? Why or Why not? Can I still NAT my users if I did it this way?
