Is there an way to avoid authentication for certain IP addresses?

We have on BM Setup:
- HTTP Proxy Enabled
- HTTP Proxy Authentication + Single Sign On + SSL Enabled
- "Authenticate only when user attempts to access a restricted page" Enabled

Access rules:
- Allow Specified IP range to Any URL (no time, no log)
- Allow NDS.CONTEXT to Any URL (no time, no log)

I've tried restarting the server and... nothing. I can't "navigate" from the
other servers.

It's a NW65SP1 + BM38 .
