I have a Windows 2008 server running with vmware workstation installed. Within VMware I have a turnkey appliance running. Assuming all ports are available and I'm using the built in firewall only to allow or deny access to the ports. The internal address of the VM is 192.168.x.x. So to access Webmin for example I would open the browser on the server and type in 192.168.x.x:12321 and it works.
What do I need to do to access the VM from outside of the server? Also, is it possible to change the default ports of webmin, phpmyadmin, etc?
