My customer currently sits in an office that he shares with his secretary. He has an XP pro laptop. She has Win 2k system. They both connect to the Internet via an old Linksys BEFSR41 (not V3, and firmware could be upgraded to 1.46.02). Their DSL account is dynamic. They both have private static addresses in the 192.168.1.xxx range. He runs ACT!, but the ACT! files are on her system. She has access to his Briefcase. He can print to her shared printers. Everything works well. However, he has decided he wants to work from home, using his laptop, (150 miles away), while she will remain in her current location. He would prefer not to lose any of the current functionality. He will have a broadband connection from home, probably also dynamic, with no router.
Question: What is the best solution?
