Forward inbound traffic from secondary WAN IP address to specific local host
I have a FortiGate 60F appliance and I have my WAN interface configured with a secondary IP address. Previously, I had only one web server on my local network with ports forwarded from the main WAN IP address to the web server's local IP address and ports.
What i need to do and haven't found anything that could help me in the docs, is to forward all the inbound requests that come through the secondary WAN IP to another web server.
I've tried with a VIP to map the secondary WAN IP address as the external IP and my new web server's local IP and the corresponding firewall policy, but no luck so far.
in addition to what Kangming mentioned (setting up a VIP to map your external secondary WAN IP to an internal server), you might also want to ensure that your ISP is properly routing the secondary IP and you're receiving requests for the secondary IP in the first place.
The 'diagnose sniffer' command Kangming mentioned can help you see if requests for the public, secondary WAN IP make it to the FortiGate.
If they do, after that further processing is up to the FortiGate policies and VIP configuration.
