FVS336GV2 Nat or Routing ?
I am trying to secure our home network a bit more before it gets "tested". I understand NAT, and I understand Routing. What I don't understand is how the FVS336GV2 can do routing without NAT or if...
- I'm not so sure that you understand NAT or why it's necessary.
Answer this question - do you need to share a single public ip between multiple devices - or in the case of a dual WAN router such as the FVS336G, two public ip addresses?
If the answer is yes, then classic routing is not an option, you MUST use NAT and this is why you're unlikely to see a comparison between the two - consider them mutually exclusive options, that do different things.
If you used the FVS336 as a classic router connected to the internet (and yes, you can use it that way), you're going to need a public routable ip address for every device on it's LAN interface
WAN Mode
The WAN mode page allows you to configure how your router should use your external Internet connections, for example your WAN1 and WAN2 port connections.
NAT is a technique which allows several computers on a LAN to share an Internet connection. The computers on the LAN use a "private" IP address range while the WAN port on the router is configured with a single "public" IP address.
Along with connection sharing, NAT also hides internal IP addresses from the computers on the Internet.
NAT (Network Address Translation)
Select NAT if your ISP has assigned only one IP address to you. The computers that connect through the router will need to be assigned IP addresses from a private subnet (example: 192.168.1.0). If your ISP has assigned an IP address for each of the computers that you use, select Classic Routing.
