I am setting up a SonicWall TZ100 and have a few questions regarding the meaning of some of the address objects and how they work in route policies. For example, here are the default route policies showing:
Source Destination Service Gateway Interface
1 Any 255.255.255.255/32 Any 0.0.0.0 X0
2 Any Default Gateway Any 0.0.0.0 X1
3 Any LAN Primary Subnet Any 0.0.0.0 X0
4 Any WAN Primary Subnet Any 0.0.0.0 X1
5 WAN Primary Subnet Any Any Default Gateway X1
6 Any 0.0.0.0/0 Any 126.96.36.199 X1
X0 is the LAN, and X1 is the WAN.
So here are my questions:
1. What is the technical definition of 'ANY'? I ask this because rule 1 makes no sense to me.
2. Rule 1: What is the meaning of 255.255.255.255/32?
3. Rule 1: Gateway 0.0.0.0 - If the above was broadcast, why would it try to broadcast it to 0.0.0.0, or presumably the internet, especially since it won't work anyway?
