The packet filter checks every incoming and outgoing packet against a set of custom
rules. You can use this feature to block unwanted traffic or subscribers in very broad
to very narrow groups.

The Protocol Filter will block or allow all traffic of a particular protocol to or from an
IP Address range. This is typically used to restrict all access to internal or external
addresses.
Source and destination IPs
IP Addresses can be entered in X.X.X.X/N format where
N is the netmask in bits. For example, you can enter values like
192.168.1.0/24 or 192.168.1.254/32. To specify "all" you can
enter "0.0.0.0/0".
Protocol Type
Select the protocol to block.
Permission
Set the mode of the filter.
Deny
blocks packets that match the
filter.
Allow
permits all packets that match the filter. Allow rules
take precedent over Deny rules, so you can create broad blocking
rules then just allow the specific traffic you want.
