- 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.

From another machine
nmap -p 1164 -sV <host> sudo nmap -sU -p 1164 <host> nc -zv <host> 1164

Is it safe to open port 1164?
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 1164 is open?
On Linux run "ss -ltnup 'sport = :1164'", on macOS "lsof -nP -i :1164", and on Windows "netstat -ano | findstr :1164" to see the local process. From another machine, "nmap -p 1164 <host>" shows whether it is reachable.
