NAT - Outside network can access specific computer.

[echebureche]

Hi All,

Can anyone help me how to allow outside network to access one specific computer inside the office thru NAT.

Cisco Device: ISR4331

PC IP: 10.1.40.36

Please see sample config below:

!
interface GigabitEthernet0/0/0
description ***TO INTERNET***
ip address 192.168.1.74 255.255.255.248
ip nat outside
duplex auto
speed auto
!
interface GigabitEthernet0/0/1
***TO CORESW***
ip address 172.254.6.1 255.255.255.0
ip nat inside
duplex auto
speed auto

interface Vlan1
no ip address
!
ip classless
ip route 10.254.0.0 255.255.0.0 172.254.6.2
ip route 0.0.0.0 0.0.0.0 192.168.1.73

ip access-list extended NATING
permit ip 10.1.40.0 0.0.0.255 any
!

here is the example for bidirectional NAT ( if you have all the routing and other setup done)

ip nat inside source static 10.1.40.36 x.x.x.x
ip nat outside source static x.x.x.x 10.1.40.36

Hi Sir Balaji.bandim
