I'm running a server with l4d2, and I noticed that some strange clients
connected to my server with those ports:

I know they are not default ports for L4D2 ,
anyone knows it's normal or anything else?

I've checked those ports on my PC and they are all closed.
those clients connected to my server and disconnected in about 30-60 secs.

all of the clients are connected through different ports, thats how udp works

Thank you Zephyrus,
But default ports for L4D2 aren't like this?

The incoming port on your server isn't the same as the outgoing port from the game client (which is relatively random iirc). For example, I'm connecting to forums.alliedmods.net port 443 (https) from my PC port 59780 to post this.

(Note: I looked through the output of netstat and chose one of the connections to this site, so it probably is on a higher port than that since HTTP closes the connection 10 seconds or so after finishing)

The client can connect using whatever port they want. The port you are seeing from the client is the port their connection is going out of on their PC, not the port on your PC that they are connecting to

Ok,so it's nothing special ,right?
Thank you Powerlord and Yamikaitou ;)
