Re: WTF?? ISA 04 semantics inbound or outbound

I'm with Mike... it's like the double negatives in group policy..... so no means yes, right?

Mike,

Think of the direction from the perspective of the From network. In that the traffic is outbound from the External network, in the SBS RWW Inbound access rule. So if you were on the external network you would need to send the traffic out that network in order to get to the To network. Thus, the rule you mentioned is configuring it such that traffic from the external network can go out to the localhost network (which is the server). It is a little different than the ISA 2000 way of thinking when you had basically an external network and an internal network, with ISA 2004 you may have multiple networks so you need to be able to define the relationships (route vs. nat) between them, as well as, the direction/flow of the traffic (outbound/inbound) between them.

Hi Doug,

that I can understand....but....

As I posted, this rule is tcp outbound, to localhost, from external???? Oh, wait a sec...external NIC? Outbound from the internet to the external NIC? Then whay ever have something called inbound? Everything could just be outbound from somewhere else????

The logic does not make sense to me AT ALL. I would think that all terminology would be as related to ISA itself.

Doug, this is not at all pointed at you but the ms thought process such as it is sometimes...



A helicopter with a pilot and a single passenger was flying around above Seattle when a malfunction disabled all of the aircraft's navigation and communications equipment. Due to the darkness and haze, the pilot could not determine the helicopter's position and course to get back to the airport.

The pilot saw a tall building with lights on and flew toward it, the pilot had the passenger draw a handwritten sign reading "WHERE AM I?" and hold it up for the building's occupants to see.

People in the building quickly responded to the aircraft, drew a large sign, and held it in a building window. Their sign said "YOU ARE IN A HELICOPTER."

The pilot smiled, waved, looked at his map, determined the course to steer to SEATAC airport, and landed safely.

After they were on the ground, the passenger asked the pilot how the "YOU ARE IN A HELICOPTER" sign helped determine their position.

The pilot responded "I knew that had to be the Microsoft support building, they gave me a technically correct but entirely useless answer."

Mike

Thanks for using Microsoft Online Support

The inbound and outbound in ISA2004 translates more to source and
destination. For example when a client try to access something on the
server. That is outbound from the lan to the localhost. Traffic from the
server to the lan would be outbound from the localhost to the internal
network. Traffic from the internet to the server is outbound from the
internet to the external network card.


I hope this helps
