NAT
Step 5.d ¡ X
Insert a One-to-One
(Bidirectional) Rule
The above three modes allow LAN/DMZ-to-WAN
sessions
establishment
WAN-to-LAN/DMZ sessions. WAN-to-LAN/DMZ
sessions are allowed by Virtual Server rules. You
can make the One-to-One NAT in the above to
incorporate the WAN-to-LAN/DMZ feature by
selecting the One-to-One (Bidirectional)
from the Type. Note that WAN-to-LAN traffic will
be blocked by the Firewall in default. You have to
add a Firewall rule to allow such traffic. If you
expect a LAN host to be fully accessed by public
Internet users, use this mode. Note that this mode
is extremely dangerous because the host is fully
exposed to the Internet and may be cracked.
Always use Virtual Server rules first.
