Expert Net Control 2312
Configuration
Use DHCP: Select "yes" if the TCP/IP settings should be obtained directly from the DHCP server:
When the function is selected, each time the device powers up it is checked if a DHCP server is
available on the network. If not, the last used TCP/IP setting will be used further.
All IP changes will take effect directly, there is no need for a restart of the firmware.
Configuration - IP ACL
3.2.4
Reply ICMP ping requests: If you enable this feature, the device responds to ICMP pings from the
network.
Enable IP filter: Enable or disable the IP filter here. The IP filter represents an access control for inco-
ming IP packets.
Please note that when IP access control is enabled DHCP and SNMP only work if the appro-
priate servers and clients are registered in the IP access control list.
IP Access Control List
The IP Access Control List (ACL IP) is a filter for incoming IP packets. If the filter is active, you can
only connect to hosts and subnets whose IP addresses are entered in the list.
Examples:
Entry in the IP ACL
Meaning
192.168.0.123
the PC with IP Address „192.168.0.123" can access the device
192.168.0.1/24

If you choose a wrong IP ACL setting and locked yourself out, please activate the Bootloader Mode
and use GBL_Conf.exe to deactivate the IP ACL.
