Thanks again, everyone.

I'm basically going to get a quote on the FVS124G from a friend of mine
who runs a computer store tomorrow...he said that it's going to be
tough to get (which I expected), but hey, that's why you have friends,
right? To abuse them and take advantage of them? Yeah, thought so. :)

The 75 feet is a nuisance, but not the end of the world. Just run a CAT5
cable over from it to one of the WAN ports on the Dual WAN router. (and
yes,
you can get a Xincom in Toronto - they're sold by TigerDirect.ca, amongst
other places.)

Your existing router would be surplus to requirements. You wouldn't have
much in the way of outbound traffic routing to a specific WAN, though
there
is the ability to point specific traffic to specific connections on some
of
the Xincom routers. Incoming is no issue - you use your DNS to manage
that.
(So, for example, if you want mail to go to one address, but not the
other,
just set up your MX records to enable that.)

I'm sitting here in BC on the Sunshine Coast, with a DSL connection and
a
Cable connection. I have my MX records pointing to the DSL line, as
primary,
with my Cable line as secondary. My web surfing, etc., is routed 75% over
the Cable, and 25% over the DSL line. When I RWW in, I _always_ come over
the DSL line, since the upload speed on the cable stinks.

Thanks, Charlie and Blenky.

Here's the problem with that idea, though, and I really didn't make it
clear in the diagram: The server and the fax (the line the DSL modem
would be hooked up to) are in adjacent rooms...but the cable modem is
approximately 75 feet away across the office itself.

I like the idea, but I can't see it being feasible...assuming I could
even purchase a dual WAN router (I'm in Toronto, and up until you two
mentioned the idea, I never knew they existed...nice idea, though, like
I said.)

The cable modem already has a router attached to it as well, and I was
hoping not to have to waste equipment. I can deal without the failover
(although it would be nice).

I'm also not sure if the SBS has two NICs (we just got it and I haven't
looked at it closely yet...that, and I usually work remotely)...would I
really need them if both routers (or if I can figure out something
else, dual WAN router) went to the hub and then from the hub to the
server?

Thanks.

Your best bet here, IMHO, is to use a dual WAN router. Most can handle
the dynamic DNS required on your cable link directly (and if not, you
can easily manage it using something like DirectUpdate), while your
static IP address will come in via DSL. Set your DNS records
appropriately, and all should be fine.

For dual WAN routers, I'm partial to the Xincom line - you do NOT need
VPN capabilities, generally, since your SBS server will usually be the
end point of any VPNs, not the router.

This is going to sound like a rather oddball scenario, but here goes:

I'm working on a network of about 30 computers inside the network and
a
server running Small Business Server 2003 Standard Edition. We're
getting Microsoft CRM put on the server and we need to have a static
IP
for it.

The problem is that DSL in the area is not fast enough to support all
of the users and the CRM/Exchange Server simultaneously. And any
kind
of a connection that would (5 MB or higher fibre connection) costs in
the 4-digit range, which I can't justify. We do, however, have an
existing cable connection (which doesn't offer true static IP
service,
or this would all be solved.)

So...my idea is to use a DSL connection and a cable connection
simultaneously.

I made a diagram outlining what I want to do below:

http://216.89.218.233/public/dsl-cable-diagram.gif

The cable modem already has a router, so I don't need one there. I
would need one for the DSL modem, though, which is fine.

So...here's what I'm thinking of doing:

1) Close all ports on the cable router (since it's not being used
for
anything other than web browsing and basic connectivity anyway).

2) Open up whichever ports on the DSL router need to be opened to
get
CRM and Exchange Server to work (I don't really know what those are,
so
if anyone could help out that way, that'd be great...although I could
find this for myself.)

3) Configure the server to accept traffic from the DSL modem
only...although I'm not 100% sure how to do that either.

Is this logical? And if it is, what would I need to configure on the
SBS to get it to work? The router's not a big deal...just open up
ports or if worse comes to absolute worst create a DMZ for the server
and away we go. But the SBS would be the part that would throw me.

Thanks.
