J-Web Configuration

To configure local list antispam using the J-Web Configuration editor, you must first create your local whitelist and blacklist custom objects.

Configure a URL Pattern List Custom Object as follows:

Select Configure>Security>UTM>Custom Objects.
In the UTM custom objects configuration window, select the URL Pattern List tab.
Click Add to create URL pattern lists.
Next to URL Pattern Name, enter a unique name for the list you are creating.
If you are creating a whitelist, it is helpful to indicate this in the list name. The same applies to a blacklist. The name you enter here becomes available in the Address Whitelist and Address Blacklist fields when you are configuring your antispam profiles.

Next to URL Pattern Value, enter the URL pattern for whitelist or blacklist antispam filtering.

Note: URL pattern wildcard support—The wildcard rule is as follows: \*\.[]\?* and you must precede all wildcard URLs with http://. You can only use “*” if it is at the beginning of the URL and is followed by a “.”. You can only use “?” at the end of the URL.

The following wildcard syntax IS supported: http://*.juniper.net, http://www.juniper.ne?, http://www.juniper.n??. The following wildcard syntax is NOT supported: *.juniper.net , www.juniper.ne?, http://*juniper.net, http://*.

Click Add to add your URL pattern to the Values list box.
The list can contain up to 8192 items.
Click OK.
If the configuration item is saved successfully, you receive a confirmation and you must click OK again. If it is not saved successfully, you can click Details in the pop-up window that appears to discover why.

Note: Because you use URL Pattern Lists to create Custom URL Category Lists, you must configure URL Pattern List Custom Objects before you configure a Custom URL Category List. URL Pattern List Custom Objects are described in the previous section.

Configure a Custom URL Category List Custom Object as follows:

Select Configure>Security>UTM>Custom Objects.
In the UTM custom objects configuration window, select the URL Category List tab.
Click Add to create URL category lists.
Next to URL Category Name, enter a unique name for the list you are creating. This name appears in the Address Whitelist list when you configure antispam global options.
In the Available Values box, select a URL Pattern List name from the list for bypassing scanning and click the right arrow button –> to move it to the Selected Values box.
Continue to add URLs or IP addresses in this manner.
Click OK to save the selected values as part of the custom URL list you have created.
If the configuration item is saved successfully, you receive a confirmation and you must click OK again. If it is not saved successfully, you can click Details in the pop-up window that appears to discover why.

Now that you have created your whitelist and blacklist custom objects, you can configure antispam filtering to use those lists.

Select Configure>Security>UTM>Global options.
Select the Anti-Spam tab in the right pane.
Under Anti-Spam , select an Address Whitelist and/or an Address Blacklist from the list for local lists for spam filtering.
These lists are configured as Custom Objects and are made available for selection here.
Click OK.
If the configuration item is saved successfully, you receive a confirmation and you must click OK again. If it is not saved successfully, you can click Details in the pop-up window that appears to discover why.
Select the Anti-Spam tab in the left pane under Security.
Click Add to configure an anti-spam profile.
The profile configuration pop-up window appears.
In the Profile name box, enter a unique name for the antispam profile you are creating.
If you are using the default server, select Yes beside Default SBL server. If you are not using the default server, select No.
If you select No, you are disabling server-based spam filtering. You would disable it if you are using only local lists or if you do not have a license for server-based spam filtering.
In the Custom tag string box, enter a custom string for identifying a message as spam.
By default, the devices uses ***SPAM***.
In the Actions list, select one of the following: Tag subject, Block email, or Tag header.
Here you are selecting the action to be taken by the device when spam is detected.
Click OK to save your profile.
If the configuration item is saved successfully, you receive a confirmation and you must click OK again. If it is not saved successfully, you can click Details in the pop-up window that appears to discover why.

Next, you configure a UTM policy for SMTP to which you attach the antispam profile you have configured.

Select Configure>Security>Policy>UTM Policies.
In the UTM policy configuration window, click Add to configure a UTM policy.
The policy configuration pop-up window appears.
Select the Main tab in pop-up window.
In the Policy name box, enter a unique name for the UTM policy you are creating.
In the Session per client limit box, enter a session per client limit from 0 to 20000 for this UTM policy.
In the Session per client over limit list, select one of the following: Log and permit, Block.
This is the action the device takes when the session per client limit for this UTM policy is exceeded.
Select the Anti-Spam profiles tab in the pop-up window.
From the SMTP profile list, select the antispam profile you are attaching to this UTM policy.
Click OK to save your policy.
If the policy is saved successfully, you receive a confirmation and you must click OK again. If the profile is not saved successfully, you can click Details in the pop-up window that appears to discover why.

Next, you attach the UTM policy to a security policy that you create.

Select Configure>Security>Policy>FW Policies.
In the Security Policy window, click Add to configure a security policy with UTM.
The policy configuration pop-up window appears.
In the Policy tab, enter a name in the Policy Name box.
Next to From Zone, select a zone from the list.
Next to To Zone, select a zone from the list.
Choose a Source Address.
Choose a Destination Address.
Choose an Application.
Do this by selecting junos-smtp (for antispam) in the Application Sets box and clicking the —> button to move it to the Matched box.

Next to Policy Action, select one of the following: Permit, Deny, or Reject.

Note: When you select Permit for policy action, several additional fields become available in the Applications Services tab, including UTM Policy.

Select the Application Services tab in the pop-up window.

Next to UTM Policy, select the appropriate policy from the list.

This attaches your UTM policy to the security policy.

Note: There are several fields in this pop-up window that are not described in this section. See the section on Security Policies for detailed information on configuring security policies and all the available fields.

Click OK to save your policy.

If the policy is saved successfully, you receive a confirmation and you must click OK again. If the profile is not saved successfully, you can click Details in the pop-up window that appears to discover why.

Note: You must activate your new policy to apply it.
