2.3.3 Section [IBNInterface]
Description
The settings in this section affect interface X127.
EnableDHCP_IBNNet
If this variable is set to 1 then this prevents the start of the DHCP server at the
commissioning interface X127.
Value:
Default:
DisableIBNNet
If this variable is set to 0, then the commissioning interface X127 is not initialized and is thus
not available.
Value:
Default:
EnableSysNetToIBNForwarding
If this variable is set to 1, it is possible to transmit packages from the system network (X120)
to X127. A firewall usually prevents this.
It is important to remember that there is no NAT involved, and the sender is responsible for
ensuring (with a suitable routing entry, for example) that packages sent to the PG or service
PC on X127 with the address 192.168.215.x only reach the NCU to which the device is
connected.
Value:
Default:
DisableIBNForwarding
If this variable is set to 1, the NAT transfer of packages from the service connection X127 to
the system network (X120) is deactivated.
Value:
Default:
