Several public IP adresses, Two Servers, One Router with one interface available

[sergio.yanez.abe]

Hello everybody, I am a new Networking administrator.

I have two servers inside my network and I want each to have a public IP address outside my border router, it is something like:

                        Private IP address                        Public IP address

Server-1             192.168.0.1                                 190.100.100.1

Server-2             192.168.0.2                                 190.100.100.2

But my problem is that I only have one router with only one interface available, and it only allows me to configure one public IP address.

I tried the following configuration using NAT.

interface GigabitEthernet0/1

ip address 192.168.0.254 255.255.255.0

ip nat inside

interface GigabitEthernet0/2

ip address 190.100.100.3 255.255.255.248

ip nat outside

ip nat inside source static 192.168.0.1 190.100.100.1

ip nat inside source static 192.168.0.2 190.100.100.2

ip route 0.0.0.0 0.0.0.0 192 190.100.100.6  (public ip pool gateway)

But no success, from internet I can ping to 190.100.100.3, routers public ip address, but I can't reach 190.100.100.1 or .2

Please, help

Regards

Sergio

Hello Ganesh and thanks for the response:

This is what I get after sh ip nat translations:

Pro Inside global Inside local Outside local Outside global
udp 190.100.100.1:51906 192.168.0.1:51906 125.90.93.203:9800 125.90.93.203:9800

After I ping my servers from internet it´s still the same, I recognize that 200.87.100.40 is our ISP dns

Thanks again and regards
