I have a problem with forwarding port 80 from the outside world to port 8090 on my computer, where is my www server. When im forwarding from any other port its ok. I'm giving my customers addres www.<my_address>:8090 for example and it works. I called to my ISP to ask is port 80 bloked. And they said that it is not. It is problem inside my router which is bloking port 80. I don't know why he is doing this, and I don't know where to change this. Please help.
