Not sure if this helps you, but it may give you an idea.
I run to PC's that are connected via LAN/file sharing, WinXP->Win98.My internet connection is LAN cable.
Both machines are connected to a USL Router, which lets them share access to the internet equally. The router assigns them the same address.
I have WINUAE installed on the Win98 machine, and can access the XP machine, as well as surf the net using AWeb from within the emualtion. OrI can access a real Amiga via serial with AmigaExplorerer,
