Re: RT-N56U with firmware version 3.0.0.3.165
This is kind of a network design question from a bit of a noob.
My ISP’s DSL “modem” is configured for DHCP on the WAN side and as 192.168.1.1 on the LAN side.
I connect the WAN side of my RT-N56U to the LAN side of the modem with “Automatic IP” and a fixed address of 192.168.1.2 (subnet mask 255.255.255.0) on the LAN side.
When I did this, the firmware reconfigured itself, explaining that I needed a different subnet for my internal LAN – which it made 192.168.2.x
So – is this a best practice? Does it really matter? My prior software version did not enforce a different subnet and seemed to work fine with a 192.168.1.2 address (v1.0.1.8i).
And this seemed weird – clients that I changed to point the gateway at 192.168.2.2 got a 192.168.2.x address. However, clients that still pointed to the old gateway address at 192.168.1.2 received 192.168.1.x addresses. This looks like the DHCP server provides addresses in either range, which doesn’t sound right.
Can someone please explain or point me to a reference where I can understand what’s happening in more/better detail?
