If you are not familiar with ISDN, be aware that any TA you use will need a
"U" interface (two-wire interface to the Telco). If your TA has an ST
interface you will need an NT1 adapter to convert the Telco 2-wire interface
to a 4-wire ST interface. Hint: NT1 = $150.00.
I only mention this because
I don't know about MS Proxy, but with any other firewall you need to make
special arrangements for FTP. The protocol won't proxy by itself and needs a
helper proxy. This is true when using the Cisco PIX firewall, Checkpoint
firewall and Linux with IPFW. There are a few other protocols that won't

I am not familiar with many of the software packages you are using, but I
have set well over 200 Internet connections on ISDN. When using both bearer
channels for connection to an ISP (for 128K) the ISP expects you to run
MLPPP (multilink PPP).

Windoze learns the default route from the ISP (taught to it by PPP).
You may be using a default route that looks like 0.0.0.0 0.0.0.0
XXX.XXX.XXX.XXX where the X's are the IP address of the router at the other
end of the PPP link. With a new ISP, the IP address of the router changed.

There can be legal implications from this. What if the user harasses, hacks

To connect two NICs together without benefit of a hub, you will need a

Don't know if this is any help, but here goes.
In my experience with multispeed NICs under Linux, I have found that some

Coming from the WAN / telecommunications world, perhaps I can shed some
light here. The rule of thumb is that the MTU should be as large as possible

Does anyone know of a quality service that will point DNS to an IP address?
IPX = Internet Packet Exchange. It is another protocol like TCP/IP and is
used primarily for Novell Netware networks. It in no way belongs on an
Internet PPP connection.
