Com’X 510 - Enable upstream network access

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

Product Line
Com'X 510

Environment
Web server

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 > set Enable Upstream Network Access to Yes

• If Network Access settings are not found on the Settings >Security >Firewall Management page, check the firmware version. The firmware must be 5.2.0 or later to enable upstream network access functionality.
• To download the latest firmware version, refer to FA274919
