Port 6881 Question

Support Technical Support

I’m getting activity on my router logs that show that LAN access is being granted via a port that is open for the Blizz Downloader.

I did some lookups on the IP’s that are connecting and noticed they were all countries out of the US. Should I be concerned about this activity and can I close that port so I don’t have unwanted connections? (pretty much a networking/security noob here so any help is appreciated)

Here is an excerpt of the log activity.

[LAN access from remote] from 153.169.124.150:9413 to 192.168.1.10:6881, Saturday, Apr 06,2019 03:41:23

Hey Istolexmas,

Port 6881 was one of the old WoW downloader ports that was used prior to the Battle.net app being implemented I believe. I confirmed that the port should no longer be needed for downloading/patching our games and it is no longer listed on our ports article.

You’re safe to close that port on your router. :slight_smile:

Thank you for the assistance Jambrix. I appreciate it. I will make sure that port is not open anymore.
