Hi there, One of my 3CX systems has recently failed, due to hackers/probes/etc - It seems the system has become overwhelmed by attacks from the internet, and its now 'failed'. My previously working setup is broken, for no real reason other than potential attacks from the internet. Typically my setups consist of Router > switch > 3CX & rest of network - with the router using its inbuilt firewall and port forward to the 3CX server. Is there anyway to prevent these attacks from happening or how have you design security around this? Also I'm now questioning a system like GXE5024, which is a PBX only (no windows) so I'm thinking this would be much more secure? Any input would be great. Thanks.
