Is there ?
I mean , I use only internal networks , even for DMZ or external links , because I feel comfortable using homogenous things in a firewall. But I was wondering why microsoft calls it 'external' and 'internal'. Why is there not only 1 and it's called 'network' or something ?

I don't know if there is a real difference, but if you look at the system policies u can see that there are some rules defined there, that use the extrenal & internal networks...
The rules are defined in a way that the internal network is protected from the external network.

Asher

hi ,

No I'm sorry I haven't been clear.
I am not referencing the default 'internal' and 'external' networks.
I mean , when you create a new network , you have a choice of a perimeter / internal / external network. But they seem to do exactly the same.
Is there a difference between them ?

Thanks Lex! I have the same question also, and was waiting for someone to ask. [Smile]

This one has been bugging me too!  I have found absolutely no difference between External & Perimeter when you define a new network.  However, I did notice a small difference when you choose Internal.  Wanna know what it is?

Answer:  When you define a new network and you choose Internal during the wizard process, you will find the "Enable Firewall client support for this network" will be automatically checked for you on the Firewall Client" tab.

So why the choice between External and Perimeter if they will give you the exact same result?  That's still a mystery.  The only thing I can come up with is MS put this in for future features.  I can only speculate that they wanted to way change the default parameters based on the network type selected in the wizard.  (Even though in the current release, there is no difference.)
