Welcome! I’ve just installed WordPress running under Ubuntu Server 8.10 (Inteprid) in a VMWare server virtual machine. As I only have one external IP address I’m currently trialling ISAPI_Rewrite by Helicon Tech as a way to reverse proxy requests from the main Windows Server 2008 machine running IIS into the virual machine. So far the following configuration seems to be working well where 10.0.0.51 is the internal IP address of the VMWare server and WordPress is configured under an Apache directory called ‘wordpress’.

# Helicon ISAPI_Rewrite configuration file
# Version 3.1.0.60
