So... do you use something like no-ip dns?

Yes I Do , because unfortunately my ISP does not support a static wan ip

so i use a program which auto detects my wan ip and gives me a static domain instead .

my friends successfully join to my server by typing :

connect my.domain:port

I've read through many tutorials but have been unable to resolve the issue myself

So "THANK YOU SO MUCH" for attention

Hi everyone

I've added a l4d server by a static domain name(domain.name :27015),but this domain is not related to a static wan ip ,the problem is that i can see 

my dynamic ip address  on the list instead of my static domain name

what should i do to show up my domain name .

thank u .
