Tip
By separating the IP address of a public server from internal
addresses, you can prevent damage to other hosts with an
internal address even if the public server should be attacked
externally.
Note
• DMZ is the acronym of DeMilitarized Zone. While using
the DMZ host function, packets can pass through the
router because of the DeMilitarized Zone, and you may
be affected by an unintended intrusion or external attack.
• The DMZ host function cannot be used for multiple PCs
at the same time.
If the incoming packet is for an address unregistered
in NAT/IP masquerade table, transfer the packet to a
host having IP address “192.168.100.10”.
