4.2.3.3 Excluded IP addresses
The entries in the list will be excluded from the protocol content filtering. HTTP/POP3/IMAP communication from/to
the selected addresses will not be checked for threats. We recommend using this option only for addresses that are
known to be trustworthy.
Add IPv4/IPv6 address – This options allows you to add an IP address/address range/subnet of a remote point for
which the rule is to be applied.
Remove – Remove selected entries from the list.
4.2.3.3.1 Add IPv4 address
This options allows you to add an IP address/address range/subnet of a remote point for which the rule is to be applied.
Internet Protocol version 4 is the older version, but still the most widely used.

192.168.0.10).
Address range – Enter the starting and ending address IP address to specify the IP range (of several computers) for
which the rule is to be applied (for example 192.168.0.1 to 192.168.0.99).
Subnet – Subnet (a group of computers) defined by an IP address and mask.
For example, 255.255.255.0 is the network mask for the 192.168.1.0/24 prefix, that means 192.168.1.1 to 192.168.1.254
address range.

2001:718:1c01:16:214:22ff:fec9:ca5).
