Remote connection setup

Hi, new to remote SQL Connections. Hoping someone can help with a definitive tutorial for setting up remote connections in SQL2005. I have a SQLExpress installation at our office behind an ADSL router. I want to connect with SQL Server Management Studio from my home PC, which is also behind an ADSL router. What settings do I have to alter, both loal amd remote.

regards
OK fixed it myself. Nothing like trial and error to overcome a problem :)
