Overview

Various Firewall ports are required to be opened for full Enabler and EEE functionality to work correctly. These are outlined below:

Enabler

Enabler Head Office Server

Required:

TCP Port 445 (Inbound from local Head Office Nodes if any exist)

Optional:

TCP Port 445 (Inbound from all stores) if using Enabler Internal Comms to transfer Nibbler Messages
TCP Port 445 (Outbound to Host Server) if using Enabler Internal Comms to transfer exported .hos files or import ISL-FILE.dat files from EEE or another 3rd party Host system.
TCP Port 9000 (Outbound to EEE Query Server) if EEE is in use
TCP Port 80 (Outbound to EEE Web Server) if EEE is in use

Enabler Store Server

Required:

TCP Port 445 (Inbound from local tills within same store)

Optional:

TCP Port 445 (Outbound to Head Office Server) if using Enabler Internal Comms to transfer Nibbler Messages
TCP Port 445 (Outbound to Host Server) if using Enabler Internal Comms to transfer exported .hos files or import ISL-FILE.dat files from EEE or another 3rd party Host system.
TCP Port 9000 (Outbound to EEE Query Server) if EEE is in use
TCP Port 80 (Outbound to EEE Web Server) if EEE is in use

Enabler Tills and Head Office Nodes

Required:

TCP Port 445 (Outbound to local server)

Optional:

TCP Port 445 (Inbound from EEE Server) if EEE Online Inventory is in use
TCP Port 9000 (Outbound to EEE Query Server) if EEE is in use
TCP Port 80 (Outbound to EEE Web Server) if EEE is in use

Further Details:

Enabler requires the standard Windows File and Pringer Sharing ports open. These allow tills to communicate with the store server.
As is often recommended, TCP port 445 should be the only port opened. Other ports such as TCP/UDP 135-139 have been known to be exploited by Malware in the past, so should remain blocked where possible.

If EEE Online Inventory is in use, specifically Online Transfers, port 445 is used to print Transfer Dockets

If EEE Query Server is in use, the TCP port number can be customised. This must be taken into consideration when opening the required ports.

If EEE is in use, the website port can be customised. This must be taken into consideration when opening the required ports.

EEE

Query Server

Used to provide answers to data queries made by stores

Required:

TCP Port 9000 (Inbound from all tills/store servers)

EEE Web Pages

Required:

TCP Port 80 (Inbound from all tills/store servers and any other devices that require access to the EEE Management Interface)

Optional:

TCP Port 443 (Inbound as above) if Secure Communications is configured on the Web Server

EEE Import/Export directories

Required:

TCP Port 445 (Inbound from all Store Servers) if Enabler Internal Comms is used to transfer Import/Export data to and from a store server.
