Allow And Block Rules - Nokia IP40 User Manual

Setting Up the Security Policy in IP40
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).

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 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. In the Navigation Bar, click Security.
The Firewall page appears.
2. Click on the Rules tab to add any rule.
3. Click on Add Rule button on the Rules page to select the type of rule that you want to add.
Depending on the tab you select, the Allow and Forward rule or the Allow Rules or the Block
Rules page appears.
