Security: TCP/UDP Filter Configuration
By selecting the TCP/UDP port, the network administrator can
optionally block some specific applications. There are two kinds of
protocol filter functions.
Allow Mode
The ”forward” function makes the switch forward the selected
protocol and drop other protocols.
Deny Mode
The ”deny” function makes the switch drop the selected protocol
and forward other protocols. The protocol is checked at the
selected secure WAN port. And it should be set at the server side.
The figure shown above illustrates how this function is applied to
the real environment.
Note:
The TCP/UDP Filter’s user-defined Port-Range is in
QoS Setting’s Class of Service
