Hi Shawn,

Boy, you can say that again. PPPoE is rotten to the core. I hear that a
lot with my gamer friends.

You'll be much happier with the static IP thing, pppoe is raw evil.  ISA
will work beautifully, won't need the linksys.  You actually will only
need 1 address if it's only the ISA that will be publicly addressed.  If
you want a dmz segment then you'll need more.

I am about to have to change ISPs as well, and are going to DSL with 30
static IP.
Am I going to have to use a nat device in front of the ISA (2000) as
well?
Or will the static IP fix that problem?
I have my web sites, terminal servers, et all published through ISA and
don't want an extra device screwing all that up.
Thanks

Isn't this how it should be .

I have a Netopia DSL router in front of ISA .. and works fine . 
The router has one public for its interface. All other public ips are
configured on external interface of ISA and configured for publishing .

Double-post.
Need some help getting ISA to work on a DSL connection. The only way I
seem to be able to get to the Internet is if I put my linksys in front
of the ISA server and configure the external NIC to use the IP of the
linksys as its gateway. I also had to provide it with a static internal
IP. I'm thinking this will come back to haunt me once I begin publishing
servers and services. I've read the articles on configuring DSL, the
network interfaces, and ISA to support PPOE and have tried everything
with no success. If I don't use the linksys I'm not able to access the
Internet on any of my secureNAT clients. I seem to recall there being
some talk on this subject and wonder if anyone can advise on the pros
and cons of this type of setup, one that uses a linksys in front of the
firewall. I'm thinking I'd be better of going with a hardware solutions
or a linux firewall solution. Any responses are appreciated. 

TIA
