I hope I understand you when you say firewall client. I'm thinking you are using the personal firewall that comes with XP and you are calling that firewall client. If you are referring to the firewall client that ISA provides, ignore the rest of my mail... Even if you are on a LAN and turn on the personal Firewall on the client, the client can go out freely but nothing can come in (theoretically...) if you want, for example, to host a website on the client, you need to configure the personal firewall to allow traffic on port 80. VPN does not block anything between the client and the server; however, if anything is blocked (such as port or protocol) on the server (any server) or on the client, the communications will be blocked on that port or protocol.

I was under the impression that a tunnel precluded any firewall rules... Thanks for the response! -----Original Message----- From: Tom Mendelboim [mailto:tomerm1@xxxxxxx] Sent: Tuesday, February 18, 2003 1:49 AM To: [ISAserver.org Discussion List] Subject: [isalist] RE: VPN and XP $5 Question - a little off topic? http://www.ISAserver.org It's not your ISA VPN connection. Outlook 2K requires a few ports to be open. You will need to research which port controls the mail notification. You can run a sniffer to see which ports Exchange is trying to communicate with at the client interface. This problem was resolved with Outlook 2002.

They use their Outlook 2000 client to connect to exchange over vpn. Their outlook will not see a new message unless they click around... If we turn off the xp firewall, they see messages immediately as they come in as Exchange and mapi normally do. Is there something we can do here? Its not that big of a deal but still a nuisance... I know that this may not be directly related - but I thought perhaps someone has ran into this with their ISA VPN trials of life...
