3. To specify the port range to which the rule applies, in the Ports
column, enter the start port number in the left text box, and the
end port number in the right text box.
Note
If you do not enter a port range, the rule applies to all ports. If you enter only
one port number, the range is open-ended.
4. From the Protocol drop-down list, select the protocol for which
you wish to create a rule.
5. In the Internet IP text box, do one of the following:
„
If you are creating an Allow rule, type the Internet IP
address that should be allowed to access the defined ports
of a specific computer inside your network.
„
If you are creating a Block rule, type the Internet IP
address whose defined ports should not be accessible from
a specific computer inside your network.
Note
When in No-NAT mode, you can leave the Internet IP field empty. The rule
then applies to the entire Internet.
When you create Allow rules in NAT mode, you need to provide an
IP address. This way the IP30 knows to which computer to forward
incoming connections. On the other hand, when you define Block
rules in NAT mode, you can leave the Internet IP field empty,
which results in the IP30 blocking outgoing Internet connections of
all computers in the local network on the specified ports.
6. In the Home IP text box, do one of the following:
„
If you are creating an Allow rule, type the IP address of
the computer inside your network, to which the specified
Internet IP address should be allowed access.
