Thanks for the responses....so far from the questions that I have been
asked I am realizing that the network here was setup incorrectly (if not
incorrectly then inefficiently)....we use an ip address range of
208.196.79.0-.255 for all of our pc's...routers etc. I think because of
this I am having trouble with the ISA server which was also set up
incorrectly.....it was originally set up with only one NIC, which I now
have learned is not the proper way to set it up. I have added a second
nic for the internal network and assigned it a 192.168.0.1 address. I
was thinking that our range of internal ip's has to be changed as well
to 192.168.0.xxx which I have done on a test workstation and will
eventually use DHCP to assign to workstations.
As you said the ISA is not really between the firewall and the clients,
it's on the same switch as the firewall and we are just pointing clients
to the proxy.

What kind of NATting is going on (actually, PATting, do be specific)?
Without listing specific IP addresses, can you give us an idea as to how
this is set up?
If I had to guess:
Internet Cloud ->
(Cisco 2600 External with the Public IP address assigned to your company
by your ISP) ->
(Cisco 2600 Internal on Private IP Range #1) ->
(Netscreen External on Private IP Range #1) ->
(Netscreen Internal on Private IP Range #2)
It also sounds like you do not have ISA between the clients and the
netscreen, but rather it is another client on your internal network, and
the clients are set to contact the ISA server as their proxy.
Do I have it right? Or does the chain I made above continue like this:
-->
(ISA External Private IP Range #2) ->
(ISA internal Private IP Range #3) ->
Clients

Thanks for the response..... here's my problem...
I am trying to setup a direct internet connection. Right now our
internet comes in through a Cisco 2600 router. The router then connects
to a NetScreen 25 firewall then a managed switch. We also have an ISA
server that is connected to this switch which is used as our proxy. All
internet traffic is routed through the ISA server then the firewall then
the router. I need to set up one direct internet connection that will
bypass both the firewall and the ISA server. I plugged into the switch
but couldn't get any internet without my proxy settings which doesn't
help me. I also tried putting a hub between the router and firewall and
plugging into that but didn't have any luck. I was also thinking of
creating a separate vlan on the switch but I am not to sure on how to
program the switch and tell it to route traffic in the separate vlan
directly to the router (if that is even possible). The switch is a 3com
superstack3 4250t. Anyone have any suggestions as to what I should do?
Thanks in advance,
Paul.

Right here... you can't use Win2k (at least not for much) without a
network...

Does anyone know of any good message boards or list servers for
networking? I have some network related issues and can't find an
answer.....
Thanks,
Paul.
