i've got this from http://support.microsoft.com/support/kb/articles/Q287/9/32.ASP The server (in this case, SQL Server) then communicates to the client by sending traffic from 1433 back to the port that the client established. The best way to observe this behavior is to trace a client-to-server communication by using Microsoft Network Monitor or a network sniffer tool. To configure the firewall, you must allow traffic from *ANY* to 1433, and from 1433 to *ANY*, where *ANY* is a port greater than 1024. *ANY* -> 1433 1433 -> *ANY* how will i create this in protocol definition? thanks' zham -----Original Message----- From: Common Sent: Friday, October 05, 2001 7:44 AM To: [ISAserver.org Discussion List] Subject: [isalist] Connect to a Sql server using internet http://www.ISAserver.org hi, we have a remote sql server, and i'm having problem connecting to it, i've already create a protocol definition for tcp 1443. do i need a secondary connection to connect? thanks' zham ------------------------------------------------------ You are currently subscribed to this ISAserver.org Discussion List as: common@xxxxxxxxxxxxx To unsubscribe send a blank email to $subst('Email.Unsub')
