Nat Mode Or Router Mode; Service Zone Network Interface - 4IPNET HSG326 User Manual

6.2.2. NAT Mode or Router Mode

Configuration Path:
NAT is the acronym for Network Address Translation which translates private IP
addresses for devices on the LAN side of a controller to routable IP before
forwarding into uplink network. Private IP addresses are invisible to devices or
routers on the WAN side of the controller, only the controller deploying the NAT
knows their corresponding translation. This mode not only protects users on the
LAN from being 'seen' by external devices but also solves the problem of limited
public IP's.
Router mode as the name suggests, is a network operating without address
translation in and out of the Controller. Router mode is selected when using public
IP or under circumstances where the downstream devices requires a routable IP
address to upstream routers.

6.2.3. Service Zone Network Interface

Configuration Path:
IP address will act as the Controller IP to a user connected to this Service Zone.
Subnet mask defines the size of your Service Zone network and defines the range
of IP's allowed to access this Service Zone. To allow users using addresses that are
out of range, enter the IP's in the Network Alias List and check Enable. Always
remember to click Apply upon completion.
There are 3 isolation options when the system is set to Tag-based mode: Inter-
VLAN Isolation, Clients Isolation, and None.
Inter-VLAN Isolation: 2 clients within the same VLAN will not see each other

when coming in from different ports. Note that Isolation is done when traffic
