Upstream Network Access
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.
