thanks for your reply ...
i give the configuration of my router
interface FastEthernet0/0 ip address 172.16.100.2 255.255.255.0 ip nat inside ip virtual-reassembly in duplex auto speed auto service-policy input block ! interface FastEthernet0/1 bandwidth 15360 ip address 115.113.163.1 255.255.255.252 ip flow ingress ip nat outside ip virtual-reassembly in duplex full speed 100 crypto map MUPUVPN service-policy output VOICEQoS
ip nat inside source route-map NONAT interface FastEthernet0/1 overload ip nat inside source static 172.16.100.8 115.113.141.145
Hi, I have internal web server with IP Address 172.16.100.8 which is natted with public ip 115.113.141.145 My requirement is that I should able to access the web server internally (on local LAN) with public ip 115.113.141.145 I checked this on Cisco and I am able to find out the following We normally define ip nat inside on local interface and ip nat outside on outside interface. INSTEAD OF THIS WE SHOULD USE ip nat enable on both interfaces to enable this. My current NAT Statement is as follows Ip nat inside source static 172.16.100.8 115.113.141.145 WHICH NEEDS TO BE CHANGED AS Ip nat source static 172.16.100.8 115.113.141.145 Let me know is this a correct way of doing this and if yes then what are the implications of this.

Hello Ravindra,

My requirement is that I should able to access the web server internally (on local LAN) with public ip 115.113.141.145
Gius> No, this should not be supported internal users should use the private ip address to access the web server. I have seen a few threads about the same issue and most of them end up with this result.
NAT action is triggered when from a NAT inside interface the traffic flow goes to a NAT outside interface.
You are asking to the router to go through NAT and then to send back the traffic to the LAN internal interface.
Hope to help
