This approach wont work.

        Lets say your default gateway is pointing to the JetStart circuit.
Traffic comes in the JetStream circuit to your XP box. The reply gets
routed out the JetStart circuit. At this point in time your screwed, as the
JetStart box will attempt to do a NAT lookup to find out how to rewrite the
packet, but it will have no record [correctly] of the packet coming in.

        What your wanting to do can be achieved with a Cisco router doing
policy routing. A Cisco 831 could probably do it, which is a dual Ethernet
router. You would plug your XP box into one interface, and your two DSL
routers into the other. This unit is around $1k.
        It may also be possible to do it with a Cisco 837 ADSL router, and
replace one of your existing DSL routers. You would set your default route
to the 837, and have it policy route traffic that was meant to be going to
the other router. The 837 is about the same price as an 831.

        The simplest approach would be to get a Cisco 1721, and put two
JetStream/ADSL interfaces into it, and let it do everything for you in one
box.
        But I doubt you would get any change out of $5k.

Subject: How to Configure 2 Jetstream Connections from Different ISPs

I have the following problem.
Two Jetstream connections on two phone lines.
One is Xtra with a fixed IP address (Jetstream Home 1000) that brings email
to our mail server and http traffic to the internal web server that we allow

some people to view. All works OK

The other is just recent and is Jetstart with another ISP with unlimited
bandwidth but no fixed IP address. It also works well. (Sometimes is faster)
Xtra one has Dynalink modem and Jetstart has an old M1122.

I have an XP machine with two ithernet cards running as a firewall to the
internal network.

If i set the default gateway on the internet ithernet card on the firewall
to either adsl modem each on works ok but when using the jetstart one as the

gateway, no email comes in from the internet.
I have connected the dynalink to the M1122 and the firewall to the M1122
and both modems are on different IP addresses.

What i want to do is have all "traffic originating here go in out the
Jetstart line and only "inbound" email and connections coming into our
server go over the Xtra connection.

Virtual Server settings are set on the Jetstream modem to correctly route
the traffic through the firewall to the internal server yet it seems when i
set the default gateway on the firewall to the Jetstart modem this incoming
traffic in unable to get through.

Any help appreciated??
