Setting the reverse direction only
There may be instances where you only need traffic shaping for incoming connections, which is in the “reverse” direction of typical traffic shapers.
To add a reverse shaper - web-based manager
1. Go to Policy & Objects > Policy > IPv4.
2. Select Traffic Shaping.
3. Select Shared Traffic Shaper Reverse Direction and select the shaper from the list.
4. Select OK.
To configure a reverse-only shaper - CLI
config firewall policy
edit <policy_number>
...
set traffic-shaper-reverse <shaper_name>
end
