NAT inside to inside on IOS, possible?

[Difan Zhao]

Hi experts,

I have a NAT configuration to NAT internal IP 192.168.1.1 and port 5900 to the interface IP (facing the ISP with public IP address) and port 59000.

ip nat inside source static tcp 192.168.1.1 5900 interface FastEthernet4 59000

I'm asked if it's possible to access the internal IP through the public IP on NATed port from the inside of the network (192.168.1.2, for example). Can this be done? I know that on the ASA it can be achieved.

Thanks!

Hi,

What you are looking to achieve?
However youa re in inside network and can be access from 192.168.1.2 to 192.168.1.1
Why you want access 192.168.1.1 through its nated public IP?

Hi,

You should be able to talk to .1 from .2 since it's you're on the same subnet. Simply do a ping test towards it.
