Traffic is wrapped in a tunnel between the two ends, so the network in between only sees the tunnel.

01 Security

Is port 4176 dangerous?

We have no specific security note for port 4176. Its risk depends on the program actually listening on it. General advice for vpn, tunnels & proxies services:

  • Patch VPN gateways quickly: they are a top initial access target.
  • Use certificates or MFA rather than shared secrets.
  • Investigate unexpected tunnels and proxies: they are also attacker tools.

03 Check it

Which program uses port 4176, and is it reachable?

Linux

sudo ss -ltnup 'sport = :4176'      # process listening on 4176
sudo lsof -nP -i :4176

macOS

sudo lsof -nP -i :4176

Windows (PowerShell)

Get-NetTCPConnection -LocalPort 4176 -State Listen | Select LocalAddress, OwningProcess
Get-NetUDPEndpoint -LocalPort 4176
netstat -ano | findstr :4176

From another machine

nmap -p 4176 -sV <host>
nc -zv <host> 4176

Block it in the firewall

sudo ufw deny 4176/tcp                                         # Linux (ufw)

04 FAQ
What is port 4176 used for?

Port 4176 is assigned by IANA to tl-ipcproxy (Translattice Cluster IPC Proxy).

Is port 4176 TCP or UDP?

Port 4176 is registered for TCP.

Is it safe to open port 4176?

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. Patch VPN gateways quickly: they are a top initial access target.

How do I check if port 4176 is open?

On Linux run "ss -ltnup 'sport = :4176'", on macOS "lsof -nP -i :4176", and on Windows "netstat -ano | findstr :4176" to see the local process. From another machine, "nmap -p 4176 <host>" shows whether it is reachable.
