Thanks for your help, everyone!
I set it up like this:
ns_section ns/server/${server}/module/nssock
ns_param timeout 120
ns_param address 192.168.1.5
ns_param hostname www.safe4all.org
ns_param port 8000
ns_param location http://www.safe4all.org
I also tried changing port to 80, and that didn't work either. Any other ideas?
