I am helping a buddy out with getting his server up. I ran him through all the steps i did to get mine up. He is using hlds and has already port forwarded the port 27015. But when he goes to start up hlds he gets the error "couldnt allocate dedicated server IP port 27015". Does anybody know whats going on? Could he have portforwarded wrong?

-Thanks for your help in advance
