5. Forwarding
For LAN  WAN communications, the gateway normally only allows you to originate an IP connection
with a PC on the WAN; it will ignore attempts of the WAN PC to originate a connection onto your PC.
This protects you from malicious attacks from outsiders. However, sometimes you may wish for anyone
outside to be able to originate a connection to a particular PC on your LAN if the destination port
(application) matches one you specify.

Check the “Delete” option of a row and then clicking “Save” button for deleting the row.
The protocol option can be Both, UDP or TCP. Both of UDP and TCP port will be blocked if “Both” was
selected.
