Hello to all.
I'm trying to configure NAT in the following toplogy:
Edge router (private network A) ------ (private network A) CiscoRouter (private network B and public network A) ------ Servers in the private nertwork B and servers in the public network A
If I configure a server in the "public network A" (IP, default GW and DNS) I can access the Internet, all fine. But now I need to configure a server in the "private network B" and do NAT in CiscoRouter to access Internet.
The problem as you can see is that I don't have a public IP Addres in the "WAN side" of the CiscoRouter, which would be the typical case of a home router NAT.
I really don't know if I can do this in a Cisco router, but in a Linux router is perfectly possible. I have the same scenario in a Linux router working perfectly.
In my case I need this two networks (private network B and public network A) to be on the "LAN side" of CiscoRouter because I need some server with private address and NAT to access the Internet and some others with public IP and direct access to/from the Internet.
Can you help me please? Do you need some network scheme to clarify?
Thanks a lot in advance and best regards.
Mauro.

Hi Mauro,
If I got correctly you question, you would do it with a similar static nat statement, assuming you have all other nat required configurations set correctly:
ip nat inside source static tcp <private-ip-address> 80 <public-ip-address> 80
Example:
ip nat inside source static tcp 192.168.0.1 80 1.1.1.1 80
