Hi Jeffrey, Are there any other ports required? Does the application require any other kind of name resolution? Thanks!

What I want to do is block all IP traffic except for the oracle client and server. I used RRAS packet filters to block all ports except TCP 1521, but oracle client can not communicate with server in the other side. What do you think to prevent the communication? thanks Jeffrey ------------------------------------------------------ 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 ------------------------------------------------------ Exchange Server Resource Site: http://www.msexchange.org/ Windows Security Resource Site: http://www.windowsecurity.com/ 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')
