Virtual IP and portforwarding
Device: FortiGate 60E, FortiOS 6.4.1
I am a bit ashamed to ask this, but I'm not able to correctly configure port forwarding for external access.
My goal is to make a web-interface of the office-automation system accessible from a mobile device outside the network. With all the previous routers I have used, setting this up was a matter of minutes, however with the FortiGate I really don't understand how to do this. I have watched all the videos I could find, searched and read recipes, without success.
The situation: SD-Wan zone with 2 members (2 providers who both give me a dynamic IP)
I use the FortiDDNS service. The internal IP I want to reach is 172.19.183.45 (internal port 8080). External port would be 8100.
I would like have with a link that looks like: myname.fortiddns.com:8100 to reach my office-automation system.
To achieve this I have tried to create a Virtual IP but I face an immediate first problem: what do I enter in the field 'External IP address'? In my case, this is dynamic.
Even if a enter my current WAN IP for test purposes it still doesn't work. What am I missing here?
In my old router I just enter the protocol (TCP), the public port, private IP and private port, witch WAN interface. Next I open the public port and that's it.
Help would be much appreciated.
Many thanks in advance.
