Exclude Network

[aulin]

Hello dear community,

I have IDS / IPS active on my LAN interface and I am very satisfied and everything works as expected.
There are VLANs on the LAN interface, and over 1 VLAN I make backups to other location.
How can I completely exclude this VLAN or this network? Because Gbit Traffic on IPS slows down my firewall.

Many thanks
