It needs to support IP authentication between individual organizations and third-party vendors. (i.e. Each institution must be seen as having a unique IP address.) We are able to bind multiple IPs to the single external NIC, one for each organization, and successfully pass internet traffic over each of these. On the vendor end of the transactions, however, all traffic appears to come from the primary IP address of the NIC. Is there someway to configure ISA so that, out of multiple IPs bound to the NIC, the address used by the client to request web content is also the one used by ISA to complete that transaction to the vendor? ============================================== gcb ------------------------------------------------------ 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: tshinder@xxxxxxxxxxxxxxxxxx To unsubscribe send a blank email to $subst('Email.Unsub')
