31.8.1 Creating or Editing a Custom Signature
Click the Add icon to create a new signature or click the Edit icon to edit an
existing signature in the screen as shown in
Figure 358 on page 507 .
A packet must match all items you configure in this screen before it matches the
signature. The more specific your signature (including packet contents), then the
fewer false positives the signature will trigger.

Rule
Importing Use this part of the screen to import custom signatures (previously saved
to your computer) to the ZyWALL.
Note: The name of the complete custom signature file on the ZyWALL
is ‘custom.rules’. If you import a file named ‘custom.rules’, then
all custom signatures on the ZyWALL are overwritten with the
new file. If this is not your intention, make sure that the files you
import are not named ‘custom.rules’.
File Path Type the file path and name of the custom signature file you want to
import in the text box (or click Browse to find it on your computer) and
then click Import to transfer the file to the ZyWALL.
New signatures then display in the ZyWALL IDP > Custom Signatures
screen.
