Hi all

I need some information on how to setup anti - spoofing !


On my Firewall I have four interfaces (external,DMZ,local,link)
I would like to know more about what the Valid IP Address Options means when
you 
enable spoof - tracking. I have already look at www.phoneboy.com information
on antispoofing.

For my current setup I have chosen external(our Internet link through Cisco
router ) to "Others".
The other three links sits behind the Firewall but I am not certain on what
Valid IP Address Options
to choose for them.
DMZ link to DNS server  
local link to proxy server
link link to an external network

If I choose "Any" for them, policies editor gives error !
What should these links be set to when anti-spoof tracking is enabled ?

Thanks
Niek
