u Select Granted Access to grant remote access to your Host computer to all except the IP addresses in the list.
u Select Denied Access to deny remote access to your Host computer to all except the IP addresses in the list.

w Select Single Computer (at one IPv4 address) and enter an IP address in the Address field.
w Select Group of computers (by IPv4 subnet mask) and enter the appropriate values into Address and Mask.
w Select Group of computers (by IPv4 start address & count), enter the first address in a range in the Address field, and enter the number of addresses in the range in the Number of addresses field.
w Select Single Computer (at one IPv6 address) and enter an IP address in the Address field.
w Select Group of computers (by IPv6 subnet mask) and enter the appropriate values into Address and Mask.
