Firewall, Basic Inbound with Mail Pinhole
Enter the target machine’s IP address, the Service protocol which is allowed to access that
machine, and click on Add to enable the Pinhole. Pinholes can be removed by clicking the
corresponding Delete button in the upper table.
If your ISP provides you with multiple public IP addresses you may specify a public IP
address that the inbound pinhole refers to. This is useful if you want to have multiple pinholes
to the same port on different internal PCs.
The Comments field is optional and provides you with a space to enter reminder details about
the rule/pinhole.
Considerations
The Internal IP Address has to be static, that is, not able to be re-assigned by DHCP. Please
refer to the previous section for details.
The Service defines exactly which Internet protocol is permitted to communicate through the
Pinhole. A wide choice of the most frequently found protocols is available from the drop down
menu under Service. Where an additional protocol is required simply email the address
shown and it will be added to the list.
More complex firewall configurations are covered in the next section. An example of the
Basic screen when rules have been configured in the Advanced section appears below.
