Setting up Port Redirection using WAN IP Alias
Posted by on 25 January 2012 09:41 AM
This example uses the Vigor2910 series router.
Two public IP addresses will be entered to the WAN IP alias and then use Port Redirection to map these to the internal web servers that have a private IP address.
IP addresses assigned by the ISP are: 184.108.40.206
We will redirect 220.127.116.11 to our web server (192.168.1.20)
Step 1: Enter Public IP addresses
Go to WAN>>Internet Access configuration menu.
Click on WAN IP Alias radio button
Enter the assigned public IP addresses as shown in the diagram below
Step 2: Configure Port Redirection
Go to NAT>>Port Redirection and click on the first available index.
In the next menu that appears enter the required details.
In the WAN IP pull down list select the required WAN IP Alias address. Here we have selected 18.104.22.168 as shown in the diagram below:
Now we can access the internal web server 192.168.1.20 from the Internet by using the IP address 22.214.171.124.
