I use the RUT360 with port forwarding to reach the internally connected devices from the Internet. This works so far, but I want to restrict access to these ports through the source IP address. However, only the internal IP addresses are listed for the setting options and the option -- Custom -- cannot be selected.
Does an option also have to be activated here so that the restriction to the source IP address is possible?
FW VERSION RUT36X_R_00.07.00
