How do you host the game? "Create" tab or dedicated server? Make sure that sv_public is not set to -2 or smaller.
Also make sure that the port you forwarded in your router was set as UDP or UDP&TCP, not just TCP.
And please read the server log, see if it says it successfully bound 0.0.0.0:26000 or something like that.
