remote connection to filemaker server 5 for mac

[robert J Collins]

I have a small network of 6 macs running Filemaker Pro 5 hosted by a mac running Server Pro 5.The network is connected to the internet via broadband with a fixed IP address. I would like to access this database from my mac at home via a broadband connection.

What specifically do I need to set on both machines to enable me to do this

Thanks
