- Answer only the networks that need the service (no open resolvers, relays or reflectors).
- UDP services can be abused for DDoS amplification: rate-limit or block them at the edge.
- Disable legacy test services that have no use in production.

Which program uses port 4362, and is it reachable?
Linux
sudo ss -ltnup 'sport = :4362' # process listening on 4362
sudo lsof -nP -i :4362macOS
sudo lsof -nP -i :4362
Windows (PowerShell)
Get-NetTCPConnection -LocalPort 4362 -State Listen | Select LocalAddress, OwningProcess Get-NetUDPEndpoint -LocalPort 4362 netstat -ano | findstr :4362
From another machine
nmap -p 4362 -sV <host> sudo nmap -sU -p 4362 <host> nc -zv <host> 4362
Block it in the firewall
sudo ufw deny 4362/udp # Linux (ufw) New-NetFirewallRule -DisplayName "Block 4362" -Direction Inbound -LocalPort 4362 -Protocol UDP -Action Block # Windows
What is port 4362 used for?
Port 4362 is assigned by IANA to afore-vdp-disc (AFORE vNode Discovery protocol).
Is port 4362 TCP or UDP?
Port 4362 is registered for UDP.
Is it safe to open port 4362?
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. Answer only the networks that need the service (no open resolvers, relays or reflectors).
How do I check if port 4362 is open?
On Linux run "ss -ltnup 'sport = :4362'", on macOS "lsof -nP -i :4362", and on Windows "netstat -ano | findstr :4362" to see the local process. From another machine, "nmap -p 4362 <host>" shows whether it is reachable.
