I am running my own webserver on internal port 81 and i want to make it accessible from the outside through my personal url (which is ofcourse linked to my modem's IP).
My WNR3500L (standard firmware) won't let me forward a service from a specific external port to another internal port. Port triggering (ofcourse) doesn't work, as in this case the 'trigger' comes from the outside (and port triggering only works if the request comes from the inside).
Help! :D
Sorry, but that's not a solution, that's a workaround. I want my router to be able to forward outside 80 to inside 81, like a router should. It's not practicle asking people to put ":81" at the end of an URL and a recipe to an unfindable site.
I have my own URL (www.bla.bla) which refers to my computer's (external) ip, so that's no problem at all.
To be completely clear: viewers from the outside must be able to visit my website at www.bla.bla (fictional ofcourse), which is running on a computer on my internal network at port 81. So i have to forward external port 80 to internal port 81 (to the specific internal 192.168.2.? ip of my server).
This, for one or another reason, can't be done in the original firmware.
So, your suggestion is to try one of the custom firmwares?
DD-WRT supports this:

There are separate fields for "Port from" and "Port to".
That's exactly what i need. I will check it out when i'm @ home this afternoon. Thanks for the suggestion.
