Port change from 80 to something else

I use either port 8080 or 8088 for this kind of stuff.

So you mean these ports would work in place of port 80 ?

I have a DSL modem which was provided to me by the ISP ,now the phone line goes into that DSL and an ethernet cable comes out of it and then that ethernet cable is inserted into my DLINK- DIR524 WiFi router which also has some ethernet port at the back so I inserted another ethernet cable there and plugged it into my ethernet shield that's it.
