While I can't speak specifically about Sonicwall and it's implementation...

The purpose of the DMZ is to provide a separate network for you to put your
internet facing servers in.  In most cases, this includes the application of
a separate rule set for the DMZ.  This might be a higher-end feature, I am
not sure.

The DMZ is not the same as the LAN and "ideally" you shouldn't be able to
access the LAN from your DMZ (and vice versa if it can be helped).  Point
is, the boxes in your DMZ are more susceptable to being broken into and if a
box in your DMZ is compromised, it shouldn't be able to then be used to
attack your LAN.

Does anyone know if firewall appliances usually protect its 
LAN port the same as its DMZ port?  

On my Sonicwall I can set port blocking for PCs on both the 
LAN and DMZ port.  If I block traffic to all ports for DMZ 
PCs, is the DMZ essentially the same as the LAN?  Or would 
it be not as safe as the LAN?

thanks,
Andy
