GPRS Communication with 1 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.
