Bandwidth Management、High Availability
Step 8. Add DMZ to LAN1 rule
Here we will add another rule (web from DMZ).
Select DMZ1 to LAN1 direction.
Step 9. Customize the rule
Setup the web-from-DMZ rule. Here we select
DMZ1_ALL / LAN1_ALL in the Source IP /
Dest. IP field. It means that if the packets come
from DMZ and targeted LAN1 region, we do not
need to care about its source / dest IP. If the
packets request for web traffic (source port HTTP
80), it will be put into the web-from-DMZ queue
by DFL-1500 bandwidth management feature.
Note: In the Action region, the web-from-DMZ
class was edited in the previous Step 4 before.
Step 10. View the results
We can see the result of our settings at the
DMZ-to-LAN rule direction.
