Connecting Servers over wan Link

We have Two Identical Novell 4.11 serves with SFT-III at two different locations, We have a Leased line between both locations. What I want is that I wanted both this server and clients on each side to access the other server. What are the things I will required to do. do I need tree name to be same? What about time syncronisation? Do I have to configure IP or my both serves can talk to each other over IPX (Do I need to have same different IPX No. on both serves)
I have configured my Intel routers over IPX aswell.

Thanks.
