I have a server, on my LAN which I need to appear as a specific IP address when it connects to the internet. The public IP address is bound to the external NIC of the ISAServer for publishing the server on the net for inbound connections. I've found that outbound connections from this server are not the same and need to make them so. Do I do this with the "Outgoing Web Requests" settings? Any help would be greatly appreciated. ------------------------------------------------------ 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: 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: JoePochedley@xxxxxxxxx To unsubscribe send a blank email to $subst('Email.Unsub')
