Trust power fibre dlink viper configuration

Hey guys,

Wondering if anyone currently on Trust Power fibre has configured a third party modem, specifically a dlink viper.

Trust Powers 3rd party modem settings on their website are quite vague and I can not seem to connect.

The viper modem says the 4th port can be configured with VLAN to work with fibre connections. I must be missing some specific details as the modem shows connected to the internet from the Dlink interface but no actual connection when browsing.

Thanks heaps

Todd
