to explain how IP Address works we just keep it simple with your IP's
(XR-R2-R1) Router [Interface WAN] <---192.168.0.x /24 or 255.255.255.0--> Modem [Interface LAN 1]
Router WAN IP should be 192.168.0.2 and the Modem LAN IP is 192.168.0.1 depends on DHCP Settings from the Modem. The CIDR is 24 and refers on the bit's used for the subnet in that case 24 times a 1 or four times 8bit in Binary - Decimal 255 = 11111111 - So the Subnet is like 11111111.11111111.11111111.00000000 - This means that the first three octets are not allowed to change on the IP Address - 192.168.0.x - The only octet to allowed to change is the fourth one from 00000000 to 11111111 in Dec 0 to 255 and since we use a IPv4 Protocol we are not allowed to use the first and the last Address in that range. Example: 192.168.0.0 (Network Address) and 192.168.0.255 (Broadcast Address) - The ones we are allowed to use is 192.168.0.1 to 192.168.0.254
That is were proper configuration can be of a advantage for IT-Security and Usability - Keep your ranges small - Example for the Router to Modem Network this is more then enough -> 192.168.0.2 for the XR and 192.168.0.1 for the Modem with the Subnet CIDR /30 - DEC 255.255.255.252 - Binary 11111111.11111111.11111111.111111 00
Since we look at this in the Binary view it will look like: 11111111.11111111.11111111.111111 00 = 192.168.0.0 (Network Address) 11111111.11111111.11111111.111111 01 = 192.168.0.1 - Modem LAN IP 11111111.11111111.11111111.111111 10 = 192.168.0.2 - XR WAN IP 11111111.11111111.11111111.111111 11 = 192.168.0.3 (Broadcast Address) 255 .255 .255 .252 - Subnet Mask
You can setup this Static for both Interfaces XR WAN and Modem LAN - To get rid of Re-Addressing the WAN interface when the Lease is over from the DHCP Server from the Modem - because that has to go thru a procedure every time we love to call DORA -> Discover - Offer - Request - Acknowledge - With Static IP's there is no need for the device to process all this.
XR Example WAN IP Settings:
IP Address: 192.168.0.2
DNS1: 184.108.40.206 Cloudflare
DNS2: 220.127.116.11 Cloudflare
Modem LAN IP Setup:
DHCP = Off
LAN IP also Device IP = 192.168.0.1
Subnet = 255.255.255.252
On the XR LAN Side you are totally fine and can keep it as is. ^^
No it's not possible to do that, the features may be implemented in the future but that is up to Netgear. We only sell the R2 direct from netduma.com and we can offer 1 working day delivery to Germany.
Hello NetDuma-Team / NetDuma Community,
did I just bone myself on buying a XR1000?
Are there any new features coming out?
The reason why I ask is that there is a DumaOS ver. 3 for the R2 but think that those features will never make it on the XR1000.
Many thanks in advance
P.S. Or did I misunderstand something major?
