How to Internet-share an USB ISDN Terminal with Virtual Machine XP or XP Pro

The following description of how to share an USB-connected ISDN Terminal (modem) with the XP VM was found more with trial-and-error than with either help from Parallels support (apparently helpless) or the input from a number of friends from this and other forums. Special thanks goes to Senior Member joem!

(Bridged Ethernet can not work for USB, because it is designed for Ethernet connections.)

There are three main areas for correct settings.

Parallel should be updated, the VM started and under Menu Item Actions, Install Parallel Tools executed, but only after the VM has completed the booting.
Your Mac gets restarted.

MAC —> System Preferences —> Network —> Show: Network Port Configurations: Check-mark your
USB Terminal/modem driver
Parallels NAT
Built-in Ethernet (This is necessary)
These Port Configurations can be dragged to the order your want them to be addressed.

Setting for your USB Terminal Driver:
PPP: check that U/N and P/W are correct, as well as the dial-in phone number
TCP/IP: Enter one or two DNS Servers for quicker connection
Proxies: you would know
Modem: choose the MLPPP modem driver for your USB Terminal which gives you 128K and allows you to accept and make phone calls while on line.

MAC —> System Preferences —> Sharing —> Internet
Turn Internet Sharing Off to make changes
Share your connection from Parallels NAT to computers using:
Built-in Ethernet
Start Internet Sharing

(Note: if you want wireless machines to connect using your ISDN connection you must change this setting each time to: Share your connection from: [your USB Terminal driver] to computers using AirPort.)

[The Ethernet Adaptor (en3) interferes with Parallels Shared Networking and must be turned off. To do this open System Preferences -> Sharing -> Internet, stop Internet Sharing and uncheck Ethernet Adaptor (en3) in To computers using list. Start Internet sharing again and check that setting are as described before.]

PARALLELS
was hopefully updates, followed by a restart.
Menu Edit —> Virtual Machine
choose Network Adapter if present, and if not choose Add... and add Network Adapter
Device Status:
Enabled checked
Connect cable at startup checked

Emulation
Shared Networking checked
Start VM

VM - WINDOW XP Settings
go Network Connections (for instance by going Start —> Control Panels —> Network Connections) —> LAN or High-Speed Internet —> Properties —> General tab - and check the following
Parallels Shared Folder Network Provider
Clients for Microsoft Networks
File and Printer Sharing
Internet Protocol (TCP/IP) double click on it and set one or two DNS server addresses.
Okay.

You should connect. If not, ascertain under the USB Icon below Window's bottom Toolbar, that your modem is NOT checked.

If your USB modem was not checked, now is the time to restart your machine, check all settings as listed here, and if it still does not work, post your specific symptoms NOT to this "How To" forum, as it was designed for solutions, but to

Parallels Desktop for Mac, to discuss technical issues arising when using Parallels Desktop for Mac. You may also PM me, as I am not always here.
---------------------------------------------------------------------------------
---------------------------------------------------------------------------------

If the above did not work for you and you need some more time to re-check and make it work, and if you must use the Internet in the VM right away,
you can disconnect your ISDN Terminal on the Mac side.

Start Parallels and the VM
Go to the USB Icon below Window's bottom Toolbar and make sure that your ISDN Terminal/modem IS checked by clicking in it.
XP will recognize a new device and will ask you to install drivers from a CD, or a location on your hard drive, or the shared folder.

Then open Network Connections and add Dial-up location.
General tab, see that under Connect using: the ISDN driver is chosen. Enter phone number of your ISP.

Under Networking tab, make sure these are check-marked:
Parallels Shared Folder Network Provider
QoS Packet Scheduler
Internet Protocol (TCP/IP) double click on it and set one or two DNS server addresses for faster connects. If you have no DNS addresses, it will usually work without them.

Connect. You might get an OS error message that a USB device was disconnected, but the VM should connect you using the USB port directly, so that you can use the Internet.

---------------------------------------------------------------------------------

And lastly, but least desirable for my taste and usage, you can connect to your ISP in XP and share as a network back to the Mac. Both machines are after all merely nodes on the LAN. This is best done with a static IP on the Mac side.
---------------------------------------------------------------------------------

[Special note: In case you need Bridged Ethernet and
Host-only Networking. They are often grayed and in some cases the following routine in Terminal will help them come choosable when followed by a restart.

[Open Terminal and copy and paste:
sudo /Applications/Parallels/Parallels\ Desktop.app/Contents/Resources/PvsvnicConfigure
after the
then, say:
sudo killall -HUP pvsnatd
Close Terminal. ]
