Solution #00004247
Scope:
This solution applies to all Barracuda Web Application Firewalls, models 460 and above.
Answer:
You can forward the source IP/client IP to the backend servers. By default, this is turned on and the header "X-Forwarded-For" contains the client IP/source IP.
With the exception of a Web Application Firewall model 360, you can customize this header. Click on Web sites > Web Site Translations > Request Rewrite and choose the web site where you would like to make the change.
You can edit the default rule (default-req-rewrite-rule) by clicking on Edit. Change the header name from "X-Forwarded-For" to the custom header name that you want.
