From your question below, you first mentioned that you could ping, in your second response you mentioned you could not and that you have your Exchange profile defined using the physical IP address of your Internal MX server. First check to make sure all the required Exchange services are running, verify that you can connect to your Exchange server from another computer from your Internal Private network, once you have confirmed that the Exchange server is working fine and that your mailbox is valid and all the protocols are enabled on the Exchange server per account, because you can disable HTTP, IMAP4, POP3 and LDAP on a per mailbox basis. Do you have a default Route once you open your tunnel? Do you have any Input or Output filters enabled? Do you have DHCP enabled on the private interface? and are you getting a IP address? Check all the basics and then lets move forward if you have not stumbled onto your problem looking at these suggestions first. -----Original Message----- From: sboticario [mailto:sboticario@xxxxxxxxxxxxx] Sent: Monday, May 05, 2003 4:27 PM To: [ISAserver.org Discussion List] Subject: [isalist] RE: VPN Connection (PPTP) http://www.ISAserver.org I have the ip address and when i have the vpn connection open i can't ping uExchange sing the machine name... -----Original Message----- From: Glenn Maks [mailto:gmaks@xxxxxxxxx] Sent: segunda-feira, 5 de Maio de 2003 20:29 To: [ISAserver.org Discussion List] Subject: [isalist] RE: VPN Connection (PPTP) http://www.ISAserver.org In your Outlook profile, do you have the Exchange server defined as the IP address or the FQDN? When you have the VPN connection open can you ping your Internal Exchange server using it's machine name? -----Original Message----- From: sb.
