I am looking to see if anyone has any details on best approach to secure Port 2222 on a Sonicwall Firewall to allow remote connections to ESMC Server that is located on premise. I am assisting with a Company that has many remote users that do not connect to work via VPN as they can do their jobs without VPN, but this presents an issue because I cannot push out policy changes nor can I get back agent information as to the state of these computers. KB6870 (https://support.eset.com/en/kb6870) addresses how to open Port 2222 on your Firewall to allow for Agent checkin remotely, but it does not address any securty concerns about doing so. I spoke to ESET looking for further information and none was available. I know I can list IPs that are allowed to connect via that port, but the list is too large and that is a burden on the networking staff. I am curious if there is a way to limit communications on that port to only agent exe communications, but not sure how to do that. Any ideas is appreciated. Thanks
