Accessible IP List
The OnCell G3111/G3151-HSPA uses an IP address-based filtering method to control access to its serial ports.

combination of IP address and netmask, as follows:

To allow access to hosts on a specific subnet
For both the IP address and netmask, use 0 for the last digit (e.g., 192.168.1.0 and 255.255.255.0 ).
