Siemens CP-8021

Use Cases
602 Unrestricted SICAM A8000 / CP-8000 • CP-8021 • CP-8022 Manual
DC8-037-2.02, Edition 10.2017
E.7.3 GPRS Communication with 2 IPSec VPN Tunnel
Note
Siemens recommends with this configuration the parameterization of an IP address for the local LAN
interfaces X1/X4 as a precaution. Thereby you can prevent a “lockout” due to an erroneous GPRS config-
uration.
When GPRS is activated, the local LAN interfaces X1 and X4 are operated in switch mode.
