Step 1: SSH into the router.
Step 2: Replace “INTERFACE” in the command below with the interface of the router (for example eth1.3) and issue the commands:
cd /
sudo vi etc/chilli/INTERFACE/config
Step 3:
If you want to allow certain hosts, enter them into the UAM Allowed line in this format:
www.domain1.com www.domain2.com
If you want to whitelist all subdomains of certain domains (*.domain.com), enter your domains in the UAM Domains line in this format:
domain1.com domain2.com

sudo service chilli restart
