Problem with LAN Setup, Address Reservation
Hello,
Nighthawk X10 R9000 - Router Firmware Version V1.0.4.28
The router is functioning perfectly: fyi...
However, I have three devices that I add to the LAN Setup, Address Reservation -->...
Use this as a guide, modify accordingly.
LAN address of router: 192.168.1.1
DHCP Pool 192.168.1.100 ~ 192.168.1.200
Assign a static IP, subnet mask and gateway to the Dell's NIC which is above or below the DHCP pool range specified above.
or
Re-enable the Address Reservation. Assign an IP which is (again) above or below the DHCP pool you've specified to the Dell's NIC MAC address. Leave DHCP enabled on the NIC, disable / enable the interface. It will grab the IP you specified in the reservation.
If you use my suggestion(s), the IP will never change, no device will ever get the Dell's IP and your port forwarding will work without issue.
antinode, yes, should have said 256.
As for 192.168.10.xxx, that is not the normal default though. If that is what in use, either the OP changed it for some reason, there was a typo (as in the fields that need to be changed the first 3 octets are filled in on the LAN SETUP page.
Of course 300 can't be used, but it was never suggested, so it too might have been a typo.
Yes, these are all possible for a Private LAN IP Address:
| RFC1918 name | IP address range | host id size |
|---|---|---|
| 24-bit block | 10.0.0.0 – 10.255.255.255 | 24 bits |
| 20-bit block | 172.16.0.0 – 172.31.255.255 | 20 bits |
| 16-bit block | 192.168.0.0 – 192.168.255.255 | 16 bits |
If the OP changed the default one would expect that the range of valid addresses would be known? If it was done automatically I wonder what is in front of the router? Could be part of the problem here?

So what? "the default" and "the only possible" are spelled
differently for a reason.

Your expectations may be too high.

I doubt that it was automatic, or that it is significant.
So far as I can see, the "300" was the biggest problem here. When
that gets straightened out, then perhaps Address Reservation will work
as expected, and we can get back to whatever the original problem might
have been with the "A older DELL machine".
