Those are tunneling protocols. Are you just trying to connect to the SAP server or are you trying to set up some sort of VPN tunnel to it / through to it? -Shawn -----Original Message----- From: Chris H [mailto:ntpro@xxxxxxxxxx] Sent: Wednesday, June 09, 2004 1:01 PM To: [ISAserver.org Discussion List] Subject: [isalist] Opening "Protocols" http://www.ISAserver.org I am trying to allow access to an SAP server through the ISA firewall and was told I need to allow "protocols" 51 (AH), 50 (ESP) and 500 (ISAKMP). My question is how to define the packet filters? Does the port # correspond to the protocol #? TCP or UDP? I have tried looking it up but cannot find a definitive answer . . . Much thanks!
