ISA Gurus, I just added a Verizon DLS box (Westel 327W) to my network and now I can't send any e-mail out. Here is the configuration: I have 2 NICs in my ISA Server 2004. The internal NIC has the IP range 192.168.35.0 thru 192.168.35.254. The External NIC is connected to the Verizon DSL box. The DSL box gives out the DHCP IP range 192.168.1.15 thru 192.168.1. 47. I have assigned 192.168.1.3 to the NIC that is connected to the DSL . This DSL box by default allows all traffic to exit without any interferance. I have configured port forwarding for example port 25, port 443, port 110 etc to the appropriate box. I can receive e-mail on my Exchange Server 2003 without any difficulty but whenever I send email out from one of my workstations, the email ends up in the queue on the server and just sits there. Anything I am missing here? Next, I am a little bit confused as to what kind of route configuration I need to setup between my internal LAN and the DSL IP range or if one would like to call it the DMZ. I am not sure if I can call the area of the DSL IP range as the DMZ. Or would that area be part of the External network? My plan is to add a 3rd NIC and assign the IP range 10.0.0.0 thru 10.x.x.254and call that zone the DMZ. I haven't done this yet so I am not worry about it now. My main problem is how to configure the ISA firewall again to let the email go out from my Exchange Server 2003 box. I just had this problem when I switched from my cable provider to the DSL provider. I never had this problem with my cable box which wasn't given out any private IP addresses out. I am also having problem making my verizon mail go out from my internal LAN from one of my machine which has Outlook 2003. Here are the errors I get from this workstation: 1). Find incoming mail server (POP3): Outlok could not connect to the incoming mail server (POP3). The problem could be the server name or port, or your server may not support SSL. Verify your port and SSl settings in More Settings under the Advanced tab. 2). Find outgoing mail server (SMTP): Outlok could not connect to the outgoing mail server (POP3). The problem could be the server name or port, or your server may not support SSL. Verify your port and SSl settings in More Settings under the Advanced tab. 3). Log onto incoming mail server (POP3): The specified server was found, but there was no response from the server. Please verify that th eport and SSL informatoin is correct. To access these settings close the dialog, then click More Settings and click on the Advanced tab. 4). Find incoming mail server (POP3): Outlok could not connect to the incoming mail server (POP3). The problem could be the server name or port, or your server may not support SSL. Verify your port and SSl settings in More Settings under the Advanced tab. Any help will be greatly appreciated. Thanks. Tee
