What is port-forwarding?
When router is in use, you will find router is connected to devices (such as PC,
DVR). When you receive request from outsider, you may not know what device
you should use to send request. Because a single IP alone may recognize data
transmitted externally, you may not access each of the devices. Port-forwarding
is designed to resolve this kind of problem.
If you set port-forwarding, even the same internet line may be connected to
port involved. (For more information regarding port-forwarding, refer to router manual
of each manufacturer. )
▶ DHCP Feature, Not Use
When you’re regular ID user, you can skip checking “DHCP” for use.
Fixed IP user should contact Internet provider to enter IP, subnet mask, gate, DNS address. Fixed
IP represents unique number and thus does not require setting of separate port-forwarding.
