VIP (Virtual IP – Port Forwarding)

Scenario: We have hosted a machine in the network with http (Port 80) and https (Port 443) running on it. When a remote machine will access the port 8080 it will be forwarded to port 80 to the hosted machine and port 1443 would be forwarded to 443 to the hosted machine

  

Step1.  We first need to configure the basic LAN and WAN settings on the firewall.

Step2.  To configure VIP go to,

Firewallà Virtual IPà Click on Create New and enter the following details.

Give an appropriate name.

Select the appropriate WAN interface incase if you are using more than one ISP.

Give the external IP Address and the internal IP address to which it is mapped.

Then click the option of Port Forwarding

Similarly you can create an entry for https port.

Then once you click on OK the following entries will be made.

Step3.

Now we need to create a policy to access the Virtual IP, to do so go to,

Firewallà PolicyàClick on Create New and enter the following details

Similarly you can define the policy for HTTPS as well.

Once these settings are done then the traffic on port 8080 would be forwarded to port 80 of internal server.

Similarly traffic on port 1443 would be forwarded to port 443 of internal server.
