Creating Rules; Allow And Block Rules - Nokia IP30 User Manual

To stop a service from running on a specific host
1. In the Navigation Bar, click Security > Servers.
The Virtual Servers page appears, displaying a list of services
and a host IP address for each allowed service.
2. In the desired service or application row, click Clear.
The Host IP text box of the desired service is cleared.
3. Click Apply.
The service or application for the specific host is not allowed.

Creating Rules

The IP30 checks the protocol used, the ports range, and destination
IP address when deciding whether to allow or block traffic. User
defined rules have priority over the default rules.
By default, in the Medium security level, the IP30 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.
