I relatively new to routers and how they work and I've been struggling with this for a while. I have Cisco 4331 router and I want to access my web server via the public IP address on my internal network. The local server I am attempting to access has separate public IP address from the address we are using to access the internet. Router has 4 physical interfaces and 3 are configured, one for WAN a two for LAN. I have been reading about NAT hairpin but I am not sure how to implement it in mz configuration. Please help.
