Some consultants are connecting to a Cisco VPN 3500 and we then have it
hubbed into a "dmz" with the ISA external NIC in the hub as well. So they
are VPN to the Cisco device and then I assume normal networking from there
through the ISA to the SAP server behind the ISA
[Cisco - 192.168.200.201] <---> [Hub]<--->[ISA External NIC -
192.168.200.184]
[ISA Server Internal NIC - 10.49.9.7] <--->[SAP Server - 10.49.2.184]

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?

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!
Chris
