Hi Richard, Are you saying the mail server is on the ISA firewall itself? ISA really wasn't designed as "ZoneAlarm for Windows Servers", so it could be problematic. However, you could use two ISA firewalls, in front of the Exchange Server, to provide a solution.

Due the infrastructure limitations and prohibitive costs of the most expensive telecommunications operator in the world TELKOM and also the poorest in service delivery the customer has installed an wireless broadband connection in the form of IBurst. I want to keep the ATM line for email as it's more reliable than the IBurst and use the wireless broadband for browsing services. However my problem is that ISA runs on the same server as the messaging / email solution, thus is it possible to route SMTP and IPSEC traffic to the ATM circuit and HTTP traffic via the broadband connection? From what I've read this is not going to be possible on a single server. Thanks, Richard. ------------------------------------------------------ List Archives: http://www.webelists.com/cgi/lyris.pl?enter=isalist ISA Server Newsletter: http://www.isaserver.org/pages/newsletter.asp ISA Server FAQ: http://www.isaserver.org/pages/larticle.asp?type=FAQ ------------------------------------------------------ Other Internet Software Marketing Sites: World of Windows Networking: http://www.windowsnetworking.com Leading Network Software Directory: http://www.serverfiles.com No.1 Exchange Server Resource Site: http://www.msexchange.org Windows Security Resource Site: http://www.windowsecurity.com/ Network Security Library: http://www.secinf.net/ Windows 2000/NT Fax Solutions: http://www.ntfaxfaq.com ------------------------------------------------------ You are currently subscribed to this ISAserver.org Discussion List as: tshinder@xxxxxxxxxxxxxxxxxx To unsubscribe visit http://www.webelists.com/cgi/lyris.pl?enter=isalist Report abuse to listadmin@xxxxxxxxxxxxx
