Bogons are public IP addresses that have not yet been allocated, so they may typically also be safely blocked as they
should not be in active use.

1.2.17 Configuring LAN IP Address & Subnet Mask
A static IP address of
192.168.1.1
and a subnet mask (CIDR) of
24
was chosen for this installation. If there are
no plans to connect this network to any other network via VPN, the
192.168.1.x
default is sufficient.

Note:
If a Virtual Private Network (VPN) is configured to remote locations, choose a private IP address range more
obscure than the very common
192.168.1.0/24
. IP addresses within the
172.16.0.0/12
RFC1918 private
address block are the least frequently used. We recommend selecting a block of addresses between
172.16.x.x
and
172.31.x.x
for least likelihood of having VPN connectivity difficulties. An example of a conflict would be If
the local LAN is set to
192.168.1.x
and a remote user is connected to a wireless hotspot using
192.168.1.x
(very common), the remote client won’t be able to communicate across the VPN to the local network.
