Crossover cable does exist between the modem and the ISA.
I got everything solved after I did some cleanup after one of my admins who
built the server.
For one, IP Forwarding wasn't turned on and top that with the PPTP packet
filters being configured incorrectly.

The question that jumps to mind is:
What sort of cable joins the modem to the server?
Since you're not bridged by a hub or switch, you need a crossover cable
between them.

Subject: [isalist] ISA and non-PPoE DSL
http://www.ISAserver.org
Curious to know if anyone has configured ISA to work with a non-PPoE DSL
service. I've read several articles about hot to configure ISA to work
"with" PPoE DSL service but nothing about non-PPoE DSL service.
I'm left to suspect that there isn't a setup difference with the ISA
between non-PPoE DSL service and a regular frame/T1 service to the
internet. Is this correct? Why do I have problems then?
I'm having a problem with getting my ISA to communicate to the outside
world.
I have the ethernet cable coming directly from the DSL modem and into
the external interface of my ISA server.
My external nic is setup with a static IP given by the provider, along
with the correct gateway and subnetmask.
My internal nic is setup with a static IP and correct subnetmask but no
gateway.
I've opened up access to the internet for all clients
I've enable the ICMP packet filters to test connectivity to the ISA from
a client on the internet
I can't ping anything public from the ISA, by IP or name. I can't even
ping my gateway. I have 5 clients behind the ISA that are setup as SNAT
clients and they CAN browse the internet fine, send and receive e-mail
and even use an ICA client to connect to a different company's citrix
app. I had to enable the ICA filter for this to happen so I know the
clients are going through the ISA.
I need the ISA to be able to get out to the internet because I need to
make a VPN connection with another ISA server.
