I have a strange behavior. New BM 38 server on NW 6.5. If I turn on the IP filtering the WPAD discovery will stop working. When I disable IP filtering the WPAD discovery starts working again. The web server hosting the WPAD.DAT file is on the private network. I can type in the URL (http://wpad.domain.com/wpad.dat and the file will display the contents with the IP filtering enabled.

Any ideas on what's causing this?

TIA
