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 18.104.22.168-.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. -----Original Message----- From: Sullivan, Glenn [mailto:GSullivan@xxxxxxxxxxxxxx] Sent: Tuesday, August 03, 2004 3:14 PM To: windows2000@xxxxxxxxxxxxx Subject: [windows2000] Re: ot- networking forums 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 Glenn Sullivan, MCSE+I MCDBA David Clark Company Inc. _____ From: windows2000-bounce@xxxxxxxxxxxxx [mailto:windows2000-bounce@xxxxxxxxxxxxx] On Behalf Of Farrugia, Paul Posted At: Tuesday, August 03, 2004 3:02 PM Posted To: Windows 2000 Conversation: [windows2000] Re: ot- networking forums Subject: [windows2000] Re: ot- networking forums 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. -----Original Message----- From: Sullivan, Glenn [mailto:GSullivan@xxxxxxxxxxxxxx] Sent: Tuesday, August 03, 2004 2:46 PM To: windows2000@xxxxxxxxxxxxx Subject: [windows2000] Re: ot- networking forums Right here... you can't use Win2k (at least not for much) without a network...
