Port 23546 AREAGUARD-NEO
Port 23546 is the IANA-assigned areaguard-neo port for AreaGuard Neo - WebServer (TCP).
What is port 23546 used for?
Port 23546 is assigned to areaguard-neo and uses TCP. The IANA registry describes the service as “AreaGuard Neo - WebServer”. It sits above the registered range, where most numbers are transient client ports. A fixed high port is worth documenting precisely because tooling often assumes the default.
Ports are the transport-layer address a service listens on. A client that wants to reach areaguard-neo connects to port 23546. 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 23546 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 23546
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 = :23546'Check on Windows
Get-NetTCPConnection -LocalPort 23546 -State Listen -ErrorAction SilentlyContinueBlock with UFW
sudo ufw deny 23546/tcpBlock with iptables
sudo iptables -A INPUT -p tcp --dport 23546 -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 23546 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 23546 is usually used
Most traffic on port 23546 falls into these scenarios. The demo below is a safe way to confirm the listener before you change anything.
- Serving a website, API or reverse-proxy traffic that clients reach on port 23546.
- Load-balancer and uptime checks probing the port before routing requests.
- Local development, where a browser or curl calls the service on localhost:23546.
Send a test request
Start a local web server, then ask the port for response headers. Replace 127.0.0.1 with the host you are testing.
curl -I http://127.0.0.1:23546Common problems with port 23546
Connection refused or timed out
Refused usually means the host is reachable but nothing is listening on port 23546. 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 = :23546' or sudo lsof -i :23546. 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 23546 used for?
Port 23546 (AREAGUARD-NEO) uses TCP. AreaGuard Neo - WebServer.
How do I check if port 23546 is open?
On Linux run `sudo ss -tlpn 'sport = :23546'`. On Windows run `Get-NetTCPConnection -LocalPort 23546 -State Listen -ErrorAction SilentlyContinue` in PowerShell. If the port is open, the output shows a process listening on port 23546; empty output usually means nothing is bound to it.
How do I block port 23546?
With UFW run `sudo ufw deny 23546/tcp`. With iptables run `sudo iptables -A INPUT -p tcp --dport 23546 -j DROP`. Persist the iptables rules with your distribution's netfilter-persistent or iptables-save tooling so they survive a reboot.
Is port 23546 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.
