Issue
How to enable upstream network access on Com'X 510 energy server?

Product Line
Com'X

Environment
Web server

Cause
Allowing downstream devices to access upstream network

Resolution

In Firewall Management, you can enable upstream network access
This allows downstream devices to access servers (such as DNS, SNTP, and SMTP) on the upstream network
The table below describes the downstream interface (where the message originated) and the upstream interface on which the message will be forwarded, based on your network selection

Network Option	Downstream (from)	Upstream (to)
GPRS/3G only	Ethernet Port 2	GPRS/3G
GPRS/3G and switched network	--	--
Wi-Fi only	Ethernet Port 2	Wi-Fi
Wi-Fi and switched network	--	--
2 Switched Ports (1 IP address for both)	Upstream network access not available
2 Separate Ports (1 IP address for each)	Ethernet Port 2	Ethernet Port 1

For example, with the Com’X configured to use two separate Ethernet ports, an IFE connected downstream on Com’X Ethernet Port 2 can send emails to EcoStruxure Facility Expert through Ethernet Port 1
Upstream network access is disabled by default. When enabled, access adapts to the network configuration in Network Settings
Go to Com'X 510 web server --->Settings-->Security-->Firewall Management-->Network Access--> Yes (to enable upstream network access)

If Network Access settings are not found on Settings-->Security-->Firewall Management page, check Com'X 510 firmware version. It may need an upgrade. For example, if the FW is 2.2.6, it first needs to be upgraded to 3.6.3 and then to 5.2.0 to enable upstream network access functionality
To download latest firmware version 5.2.0, refer to FA274919
To download firmware version 3.6.3, click on this link Com'X 510 v3.6.3 Firmware
