Port 4360 MATRIX-VNET
Port 4360 is the IANA-assigned matrix-vnet port for Matrix VNet Communication Protocol IANA assigned this well-formed service name as a replacement for "matrix_vnet" (TCP).
What is port 4360 used for?
Port 4360 is assigned to matrix-vnet and uses TCP. The IANA registry describes the service as “Matrix VNet Communication Protocol IANA assigned this well-formed service name as a replacement for "matrix_vnet".”. It sits in the registered range, the block used by databases, application servers and developer tooling. Port conflicts here are common when several local services start at once. The same port is also registered under matrix_vnet.
Ports are the transport-layer address a service listens on. A client that wants to reach matrix-vnet connects to port 4360. If nothing is listening, the connection is refused. That is why a port conflict appears whenever two processes try to bind the same number.
Use the commands below to confirm whether port 4360 is actually in use before you change firewall rules. Blocking the port stops new inbound traffic at the firewall, but it does not stop a local process from listening, and it does not remove the service from the machine.

Check and block port 4360
Copy-ready commands for the protocols assigned to this port. Run the check first, then block only what should not be reachable.
Check on Linux
sudo ss -tlpn 'sport = :4360'Check on Windows
Get-NetTCPConnection -LocalPort 4360 -State Listen -ErrorAction SilentlyContinueBlock with UFW
sudo ufw deny 4360/tcpBlock with iptables
sudo iptables -A INPUT -p tcp --dport 4360 -j DROPThese commands are examples for a typical host. Check the listener before you change firewall rules, and persist iptables rules with iptables-save or netfilter-persistent. On Windows, use Windows Defender Firewall or New-NetFirewallRule for persistent blocks. The iptables rules here cover IPv4; mirror them with ip6tables if IPv6 is enabled.
Is port 4360 safe to expose?
This port is not on our curated list of services with a widely exploited profile. Exposure is only safe when the listening service is intended, patched and protected by a firewall. Keep the listening service patched and remove it if unused. A default-deny firewall policy with explicit allow rules is still the safest baseline.
Where port 4360 is usually used
Most traffic on port 4360 falls into these scenarios. The demo below is a safe way to confirm the listener before you change anything.
- Application backends and supporting services that use a fixed registered number.
- Containers or local stacks that publish the port on the host.
- Firewall and exposure reviews before the service goes to production.
Probe the port
Confirm something is listening before you debug the client. This checks a TCP handshake on the port.
nc -vz 127.0.0.1 4360Common problems with port 4360
Connection refused or timed out
Refused usually means the host is reachable but nothing is listening on port 4360. A timeout more often means a firewall drop, a wrong host or a service bound to a different interface.
Port already in use
Find the process holding the port with sudo ss -tlpn 'sport = :4360' or sudo lsof -i :4360. Stop that process or configure it to bind another port; killing it without identifying it can take down a production service.
Firewall rule did not survive a reboot
UFW and Windows Firewall keep rules across restarts. Raw iptables rules do not: save them with iptables-save or the netfilter-persistent package, and re-apply after upgrades that reset the ruleset.
The port is blocked but still reachable
A firewall rule filters inbound traffic; it does not close the listener. Confirm with the check command above and bind the service to 127.0.0.1 when only local clients need it.

Frequently asked questions
What is port 4360 used for?
Port 4360 (MATRIX-VNET) uses TCP. Matrix VNet Communication Protocol IANA assigned this well-formed service name as a replacement for "matrix_vnet".
How do I check if port 4360 is open?
On Linux run `sudo ss -tlpn 'sport = :4360'`. On Windows run `Get-NetTCPConnection -LocalPort 4360 -State Listen -ErrorAction SilentlyContinue` in PowerShell. If the port is open, the output shows a process listening on port 4360; empty output usually means nothing is bound to it.
How do I block port 4360?
With UFW run `sudo ufw deny 4360/tcp`. With iptables run `sudo iptables -A INPUT -p tcp --dport 4360 -j DROP`. Persist the iptables rules with your distribution's netfilter-persistent or iptables-save tooling so they survive a reboot.
Is port 4360 safe to expose?
This port is not on our curated list of services with a widely exploited profile. Exposure is only safe when the listening service is intended, patched and protected by a firewall. Nevertheless, keep the listening service patched and remove it if unused. A default-deny firewall policy with explicit allow rules is still the safest baseline.
