How to pass referrer
information to specific Web pages
Situation:
You want to allow Norton Internet Security (NIS) or Norton Personal
Firewall (NPF) to pass referrer information to a specific Web page.
Solution:
When you click a Web page, your browser notes the current page you are
on and sends that information to the server of the new Web page. This
way, the server for the new Web page knows the last Web page you viewed.
For example, if you are on www.symantec.com and click www.microsoft.com,
the browser sends www.microsoft.com the information that you are
currently viewing www.symantec.com. If you block referrer information,
the server of the page you are requesting to see does not know what page
you saw last. By default, Norton Internet Security (NIS) and Norton
Personal Firewall (NPF) blocks this information. However, some Web pages
require this information before allowing you to view the page. If you
need to allow referrer information to pass to a particular Web page, you
must create a rule for it.
To create a rule:
1.
Open NIS or NPF.
2. Click Options.
3. Click Internet Security or Personal Firewall. This step is not always
needed.
4. Click Advanced Options.
5. Click the Web tab.
6. Click Add Site. A new site/domain box appears.
7. Enter the name of the site that you want to receive the referrer information and click OK. That site name appears in the left frame of
the Advanced Options window.
8. Click the name of the new site.
9. Click the Privacy tab.
10. Check the "Use these rules for..." box.
11. Change the Referrer from "Block" to "Permit."
Your screen should look something like this:
12. Click Apply, and then click OK.
13. Click OK to close the Options window.
How
to exclude a Web site from intrusion detection
Situation:
After you install Norton Internet Security (NIS) 2003 or Norton Personal
Firewall (NPF) 2003, you can no longer access a specific Web site
because the site is blocked by Intrusion Detection. You want to know how
to reconfigure NIS or NPF so that you can access the Web site.
Solution:
NIS and NPF maintain a list of signatures for common types of intrusion
detection. When an incoming communication includes one of those
signatures, NIS and NPF prevent your computer from receiving and
processing that communication. If the communication is from a Web site
that uses the same signature in its programming, you cannot access that
Web site.
To resolve the problem, configure NIS or NPF to allow communications
from that Web site by adding the Web server computer to the list of
Exclusions for the AutoBlock feature.The Web server computer is the
computer that you access when you access that Web site.
To exclude the computer from the AutoBlock feature:
1. Determine the Web address (an IP
address or URL) of the Web server computer.
2. Open NIS or NPF.
3. Double-click Intrusion Detection.
4. Click the IP Addresses button.
5. Click Add. You see the Specify Computers dialog box.
6. Type the Web address in the box.
7. Click OK in the Intrusion Detection window.
8. Close NIS or NPF.
You can now access that Web site in your Web browser.
More information
To determine whether your access to a Web site is blocked by Intrusion
Detection, attempt to access the Web site and then look at the NIS or
NPF View Logs for the entry that was made. If the entry includes the
phrase "Attempted Intrusion" then Intrusion Detection is
blocking access.
