Hi All,
I am having a problem and I'm trying to do a NAT configuration to do a quick-fix (I know this is not the correct solution, but I need it for the moment)....
The problem is the following:
I have an inside computer (192.168.1.80) trying to reach an internal server (192.168.2.175) using the domain name = mycompany.com
The problem is that the computer is using a public DNS server which responds with the publiic IP for the server (201.195.91.50)
So, since the computer is getting that to reach mycompany.com it should use IP 201.195.91.50 (instead than 192.168.2.175 as it should), I'm trying to do the following on my Internet router:
##########################################################################################
interface FastEthernet0/0/0
description ## Inside interface where the computers and servers reside ##
ip address 192.168.1.7 255.255.255.0
ip nat inside
ip policy route-map SERVERS
interface l0
ip add 1.1.1.1 255.255.255.255
ip nat inside
interface l1
ip add 2.2.2.2 255.255.255.255
ip nat outside
access-list 198 permit ip 192.168.1.0 0.0.0.255 host 201.195.91.50
route-map SERVERS permit 10
match ip address 198
set interface l0
route-map Loopback permit 10
set interface l1
ip nat inside source static 201.195.91.50 192.168.2.175 route-map Loopback
##########################################################################################
I'm going to explain what I'm trying to accomplish with the above configuration:
When the inside machine (192.168.1.80) tries to reach the server (201.195.91.50), the traffic will get to the FastEthernet interface, from the Route-Map Servers it will be send to Loopback 0 (where it gets NATed from 201.195.91.50 to 192.168.2.175) and through Loopback1 (so that it get NATed), and then from normal routing it will get out the FastEthernet interface again to the internal server.
Is this going to work?
Thank you!
Federico.
