The first problem, as I see it, is that this web server is not on the same network as your router.

Is that a correct understanding?

Is it in the same building and accessible?

There are a couple of ways that it can be done, but provide us with some more details... I.E. the IP subnet of the router's LAN and the IP of the web server you want to use.

Well, the firewall/router you have has two dmz ports that you can assign an IP address to that would allow access to your port 80 (http) server apparently at I do not understand or I am confused about the hookups you are using.

Your fortigate should have a LAN IP of 192,168,1,253 for your main LAN, correct?
So you have your web server connected to this fortigate as well on one of the interfaces which has an IP of I hope I have this correct.

Normally a DMZ a demilitarized zone, is open to all incoming traffic from the web/WAN interfaces. I would never put more than one machine on a DMZ as all those machines PCs and servers, are very vulnerable.

In your case, I would port forward port 80 to and not put it on any of the DMZ interfaces.

The fortigate should have a web interface that you can set up the ports, IP addresses, firewall rules and it will allow you to port forward.

I hope I have started to answer your question.

got it working using the dmz  all externall traffic coming in on port 80 gets forwarded to webserver  that works fine however i would also like to be able to work on that computer remotlely i tried making a rule saying any traffic coming from a certain ip address get forward to that same server port 3389 for remote desktop. can that work as well? the dmz port on the foritgate is that is the only to things on the 50 network

OK. So that DMZ will allow you to block all ports and allow the forwarding one port. That is great!

You should be able to allow multiple ports to forward to that IP doing the same thing you did before. As it is usually necessary in a lot of web servers to forward port 25, 80, 21 and others to that same server.
