list on the upper-right corner.
29
4. On the user-dened QoS rules page, there are four default
online service types – web surf, HTTPS and le transfers.
Select your preferred service, ll in the Source IP or MAC,
Destination Port, Protocol, Transferred and Priority, then
click Apply. The information will be congured in the QoS rules
screen.
NOTES
• To ll in the source IP or MAC, you can:
a) Enter a specic IP address, such as "192.168.122.1".
b) Enter IP addresses within one subnet or within the same IP
pool, such as “192.168.123.*”, or “192.168.*.*”
c) Enter all IP addresses as “*.*.*.*” or leave the eld blank.
d) The format for the MAC address is six groups of two
hexadecimal digits, separated by colons (:), in transmission
order (e.g. 12:34:56:aa:bc:ef)
• For source or destination port range, you can either:
a) Enter a specic port, such as “95”.
b) Enter ports within a range, such as “103:315”, “>100”, or
“<65535”.
• The Transferred column contains information about the upstream
and downstream trac (outgoing and incoming network trac) for
one section. In this column, you can set the network trac limit (in
KB) for a specic service to generate specic priorities for the service
assigned to a specic port. For example, if two network clients, PC
1 and PC 2, are both accessing the Internet (set at port 80), but PC 1
exceeds the network trac limit due to some downloading tasks, PC
1 will have a lower priority. If you do not want to set the trac limit,
leave it blank.
