This tip is provided so that you can play with a test server at home, basically, though you could actually do something like this on a small network to provide Internet access. It is intended to show
how to configure a standard analog modem connection to be used to dial an ISP.
While I was working on this, someone pointed out that Novell has written an AppNote on this subject. Check out

At this time, the instructions are fairly rough, and I mostly just put together some screen shots and noted them. The observant reader will notice that I have a screenshot or two near the end calling out a COM2_1 interface instead of a MODEM_1 interface. That is because I took up new screenshots on a test server that actually didn't have a modem to show what settings would be used, while later switching to some screenshots I happened to have of one of my test servers that did have a modem.
(The dial-up test server was down when I wrote this). The configuration should be sufficient to get you going though.
Note: You do not actually need BorderManager installed to set this up. Any NetWare 4.11 server with NIAS or MPR installed, or any NetWare 5.x server should have the menu options shown in INETCFG.
Once you get the server connected to the ISP, simply enable dynamic NAT on the modem interface, and set the default gateway of PC's on your LAN to point to the server's LAN card IP address, and they should be able to access the Internet. The PC's will also need to be configured to point to the ISP's DNS servers.
If you are using BorderManager, see tip #2 at this web site as well.
