01 Security

Is port 3359 dangerous?

We have no specific security note for port 3359. Its risk depends on the program actually listening on it. General advice for other services services:

  • Close the port if nothing on the host needs it.
  • Identify the process that listens on it (commands below) before opening it in a firewall.
  • Expose a service only to the networks that use it.

03 Check it

Which program uses port 3359, and is it reachable?

Linux

sudo ss -ltnup 'sport = :3359'      # process listening on 3359
sudo lsof -nP -i :3359

macOS

sudo lsof -nP -i :3359

Windows (PowerShell)

Get-NetTCPConnection -LocalPort 3359 -State Listen | Select LocalAddress, OwningProcess
Get-NetUDPEndpoint -LocalPort 3359
netstat -ano | findstr :3359

From another machine

nmap -p 3359 -sV <host>
sudo nmap -sU -p 3359 <host>
nc -zv <host> 3359

Block it in the firewall

sudo ufw deny 3359/tcp                                         # Linux (ufw)
New-NetFirewallRule -DisplayName "Block 3359" -Direction Inbound -LocalPort 3359 -Protocol TCP -Action Block  # Windows
04 FAQ
What is port 3359 used for?

Port 3359 is assigned by IANA to wg-netforce (WG NetForce).

Is port 3359 TCP or UDP?

Port 3359 is registered for TCP and UDP.

Is it safe to open port 3359?

It depends on the program that listens on it. Open it only for a service you know and only to the networks that need it. Close the port if nothing on the host needs it.

How do I check if port 3359 is open?

On Linux run "ss -ltnup 'sport = :3359'", on macOS "lsof -nP -i :3359", and on Windows "netstat -ano | findstr :3359" to see the local process. From another machine, "nmap -p 3359 <host>" shows whether it is reachable.
