Is port 3043 dangerous?
We have no specific security note for port 3043. Its risk depends on the program actually listening on it. General advice for media & streaming services:

Which program uses port 3043, and is it reachable?
Linux
sudo ss -ltnup 'sport = :3043' # process listening on 3043
sudo lsof -nP -i :3043macOS
sudo lsof -nP -i :3043
Windows (PowerShell)
Get-NetTCPConnection -LocalPort 3043 -State Listen | Select LocalAddress, OwningProcess Get-NetUDPEndpoint -LocalPort 3043 netstat -ano | findstr :3043
From another machine
nmap -p 3043 -sV <host> sudo nmap -sU -p 3043 <host> nc -zv <host> 3043
Block it in the firewall

What is port 3043 used for?
Port 3043 is assigned by IANA to brp (Broadcast Routing Protocol).
Is port 3043 TCP or UDP?
Port 3043 is registered for TCP and UDP.
Is it safe to open port 3043?
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. Require authentication on cameras and media servers.
How do I check if port 3043 is open?
On Linux run "ss -ltnup 'sport = :3043'", on macOS "lsof -nP -i :3043", and on Windows "netstat -ano | findstr :3043" to see the local process. From another machine, "nmap -p 3043 <host>" shows whether it is reachable.
