Custom Firewall Rules on Asus RT-N66U?

[DHR]

Has anyone had success adding custom firewall rules to to the Asus RT-N66U, just want to block anything coming from a specific IP inbound and outbound?

I have a different model, but think it should be roughly the same.

Try going to:
Firewall -> Network Services Filter

Filter type table - select 'black list'
Choose days and times it's applicable for.

Then at the bottom, enter the IP address you want to block in the 'Destination IP' column. Add the same IP address for both TCP and UDP protocols, and then apply.
