Huh I think it is posible. Ports are just a connection. Lets say he has 2 servers on port 80. I connect to server number 1, My pc would get the servers Ip address. Lets say I connect to server number 2, my pc would connect to server number 2 using its unique ip address. So now he said he has 5 web servers now those 5 have there unique IP address from were people can connect to it. BrownChild you said "So how do you direct my packets to go to your webserver 1? how would your network know i wanted to connect to server 1" All packets must have an address to go to, your isp has an address for you and therefore all his webserver will have there own onces, I suppose even if it is one ip for 5 webserver those 5 webserver will than have there own address separate to the isp address. Pc address, Aka (Also know as) IP address.
The connection is just established through port 80. By default I think all ISP have port 80 opened. but since we are in a router we will have to do it ourself. I may be wrong not all ISP have port 80 opened. Shed some lights here (you know who I mean!) As for to do it I believe I can do it.
KK after you have successfully made it to the login page
Navigate to
ADVANCED >
SPECIAL APPLICATION. Once there I believe you can take it from there. Just put 80 on both Trigger Port and firewall port. Now set TCP to both, for both of Trigger and firewall port.
Here is an image of how I would do it.

Special application is used to open up ports to all devices on the network. Making it unsafe if you open certain ports. "Special Applications rules apply to all computers on your internal network" You may at one point ask yourself what is is Trigger and firewall port? Well trigger is outbound Aka information you will send via w.e port you open. Firewall port is information you will receive via w.e (what ever) port you open up. Good luck bro! let me know how it goes.
Anyway I believe I have resolved your issues. Thank you for posting on Dgl 4500 It was a pleasure serving you.
