NAT Hairpin Cisco IOS to access webserver on FQDN from LAN.

Last Modified: 2016-01-03

Hope someone can help, I'm trying to setup NAT hairpinning on Cisco IOS version 15.4

The end users want to be able to access the web server hosted on their LAN using the public IP/FQDN.

Current static NAT rules

ip nat inside source static tcp <internalWebserverIP> 25 <PublicwebserverIP> 25 extendable
ip nat inside source static tcp <internalWebserverIP>80 <PublicwebserverIP> 80 extendable
ip nat inside source static tcp <internalWebserverIP> 443 <PublicwebserverIP> 443 extendable

Any help would be appreciated.
