Problems with PTP49400 and PTP49600 web page

I have three different links that seem to not allow me to log in to the web client on the master side but I can on the slave side. Even plugged directly into the PIDU I can only access the slave unit. These units are up and working just fine. The configuration is very basic. They were put up and aligned having only the IP address set to static. everything else is unchanged from the factory. Any info would be great.
