ESET Remote Administrator (ERA) requires certain ports to be open in order to function properly. The table below lists the possible network communications used when ESET Remote Administrator Server (ERAS) is installed. The process EHttpSrv.exe listens on TCP port 2221 and the process era.exe listens on TCP ports 2222, 2223, 2224 and 2846. Other communications occur using native operating system processes (for example, “NetBIOS over TCP/IP”).
For more information regarding ports used by ERA, consult section 2.1.3 (page 12) of the ESET Remote Administrator Manual.
| Protocol | Port | Description |
|---|---|---|
| TCP | 2221 (ERAS listening) | Default port used by the Mirror feature integrated in ERAS (HTTP version) |
| TCP | 2222 (ERAS listening) | Communication between clients and ERAS |
| TCP | 2223 (ERAS listening) | Communication between ESET Remote Administrator Console (ERAC) and ERAS |
If you are using all features of the program, the following network ports need to be open:
| Protocol | Port | Description |
|---|---|---|
| TCP | 2224 (ERAS listening) | Communication between the agent einstaller.exe and ERAS during remote install |
| TCP | 2225 (ERAS listening) | Communication between the ESET Dashboard HTTP Server and ERAS |
| TCP | 2846 (ERAS listening) | ERAS replication |
| TCP | 139 (target port from the point of view of ERAS) | Copying of the agent einstaller.exe from ERAS to a client using the share admin$ |
| UDP | 137 (target port from the point of view of ERAS) | “Name resolving” during remote install |
| UDP | 138 (target port from the point of view of ERAS) | “Browsing” during remote install |
| TCP | 445 (target port from the point of view of ERAS) | Direct access to shared resources using TCP/IP during remote install (an alternative to TCP 139) |
Firewall settings
All ports listed in the table above must be open in order for all components of ERA to properly function.
