Customizing Nokia IP40 Security Platform

Security Policy

The following sections describe how to customize your security policy.

Creating Firewall Rules

The Nokia IP40 Security Platform checks the protocol used, the ports range, and destination IP
address when deciding whether to allow or block traffic.
By default, in the medium security level, the IP40 blocks all connection attempts from the
Internet (WAN) to the LAN, and allows all outgoing connection attempts from the LAN to the
Internet (WAN).
Note
User defined rules have priority over default rules.

Allow and Block Rules

The Allow and Block rules provide you with greater flexibility in defining and customizing your
security policy. You can allow additional inbound services that are not on the virtual servers list,
or block outbound communications for specific port ranges and protocols.
To permit incoming access from the Internet to your internal network for specific port ranges
and protocols you must create a new Allow rule. To block outgoing access from your internal
network to the Internet, for specific port ranges and protocols, create a new Block rule.
To create a new rule
1. Click Security on the main menu.
The Firewall page appears.
2. Click the Rules tab to add any rule.
3. Click Add Rule on the Rules page to select the type of rule, to add.
