ZyXEL Communications ZyXEL ZyWALL IDP 10 - Manual (Page 74)

ZyWALL IDP 10 User’s Guide
6-28 IDP Policies
6.6.2 Packet Content Example
In the following example, the rule is for the IP protocol, so the payload search begins at the end of
layer-3. Three strings (S1, S2 and S3) have been defined and have been found after the Matching
Offset (10) and within the Matching Depth (70). The order in which they are found doesn’t matter.
The same matching offset and depth applies to all strings and string overlaps are allowed.
6.7 Registering your ZyWALL
Use the Registration screen to enable IDP service on the ZyWALL. You need to do tis before you
update new policies. Follow this procedure to do this.
1. Go to http://www.myZyXEL.com , ZyXEL Communications online services center.
2. If you have not already done so for another ZyXEL product, create a myZyXEL.com account
containing a login name and password. You will need a valid e-mail address to which a
subscription code is sent that validates your e-mail address and login name/password.
3. Register your ZyXEL product, for example the ZyWALL IDP 10. You will need the product
serial number and authentication code (product MAC address), which should be found on a
label in the package that contained the product.
4. After you have registered the product, go to the product details and click the intrusion policy
service Activate 1 link.
5. A screen then displays showing an Activation Key. This information is also sent to your
myZyXEL.com-registered e-mail address. Store this e-mail for future reference.
6. Log into the ZyWALL web configurator; click IDP and then the Registration tab to display
the screen as shown next.
