I have configured a few of these.
There are a few things that you have to consider. The NT box will only act
as a gateway to your network, i.e. you will have to place the NT box behind
firewalls, etc to protect your network. It does, however, support dialback.
It supports this very well. To my knowledge, there is no way to filter packets.
NT Server 3.51 will host PPP clients only. You can change the
authentication protocol to either PAP, CHAP, or CHAP with Microsoft
encryption. If your clients are Microsoft (running RASv.2 I think, that's
'95 and NT clients), you are best to go with the 3rd option. I have some
MAC clients running MAC TCP and they only understand PAP, same with Trumpet
Winsock clients (windows 3.1 clients). It's not quite listed this way, as I
remember there are 3 options labeled very different from PAP, CHAP, and
Microsoft CHAP, but that is the order. I think that PAP is listed as
"accept any authentication, even clear text." Don't know why they listed
The overhead is no more than other NT user overhead. They actually
authenticate against the NT registry. You will have to add an entry in the
registry for the user and then give them Dialup Access in the RAS
Administration program. It's really that simple.
