[KB8180] Network Configuration Requirements for allowing clients to connect to ESET PROTECT remotely (8.x – 9.x)




  • External clients must be able to communicate with the ESET PROTECT server on port 2222
  • Internal and external DNS servers must be configured to point to the correct IP address of the ESET PROTECT server based on where the client is located

Network configuration steps

  1. Create a NAT rule on your firewall/router that points traffic received on port 2222 TCP to the internal IP address of your ESET PROTECT server. 

  2. Add a new DNS record on your internal DNS server that points to the ESET PROTECT server (in the example below, a record would be created pointing avserver.example.com to

  3. Add a new DNS record via your domain name registrar that will allow clients outside of your internal network to locate the external IP of your ESET PROTECT server.

  4. Make sure that all necessary ports are open on servers and client workstations. 

Example scenario

In the example below, the external IP of the Corporate Firewall / Router is The corporate edge device is set to forward traffic on port 2222 to the ESET PROTECT server. Therefore, example.com will point avserver.example.com to so that clients external to the corporate network can communicate with the ESET PROTECT server.
