Can you prevent external clients from connecting to port 2222

Recommended Posts

Hi, 

I've recently setup our new ESMC server and was able to let external clients connect to our internal ESMC server.

Is it possible to create some sort of authentication so that people can't just connect to our ESMC server?

It's on port 2222.

If you want to temporarily block agents from connecting to the server, using iptables should work I assume:
iptables -A INPUT -p tcp --dport 2222 -j DROP

I've contacted our local Eset Callcenter and they told me that no one can reach the ESMC Server without the proper certificates. Thanks for you help anyways!

That's correct. I thought you would like to prevent existing clients who already reported to the ESMC server from connecting to it for certain time.
