IP Address Conflict
I'm not very networking savy so help me out. I am using Orbi Wifi 6 (RBK853). For some reason, my work laptop is getting assigned an IP address that conflicts with a SQL server database that I a...
Thanks for the reply. All of this is a bit over my head. See my responses below.
What happens if you change the default DHCP IP address pool range on the RBR to something like .100 to .200?

Is this what the "Use router as DHCP server" along with "starting address and ending address" is? Currently, it starts at 2 and ends at 254. My "problem" IP address is 35. This is where I was thinking if I set this to starts at 36 and ends at 254 it may solve my problem. Is that what you're suggesting above? Seems like it. I just don't want to screw something up and find myself without internet/wifi, especially since I don't know what I'm doing.
What is the 192.168.# on the VPN? 192.168.1.x? If so, try setting the RBRs router IP address from 192.168.1.1 to 192.168.0.1 and range .100 to .200 and test.
Is this the LAN/TCPIP section? On my orbi router, it is 192.168.1.1. In this approach, you're saying to change to 192.168.0.1? That would mean devices would be assigned 192.168.0.2 - 192.168.0.254 if I'm understanding correctly, right? That seems like it would work too, and not reduce my total number of available IP addresses, compared to using the above approach. Again, I'm pretty unfamiliar with all of this.
What FW version is loaded on the system?
V7.2.6.31_5.0.24. I checked for firmware updates and there were none.
Check with the VPN provider to get more information on what your system should be set to to help avoid conflicts.
The VPN is my work VPN. I've got a ticket into IT support but they haven't been very helpful. After connecting to my work VPN, if I check my IP address through ipconfig, it shows as 192.168.1.35, which is the problem IP that is assigned to the SQL server.

Yes, setting the pool range at .100 to .200 will help with your one IP address that you seen to get at .35 will avoid that. Any connected device would get nothing else besides something between .100 and .200.

Yes. Under Advanced tab/Setup/LAN setup. Make the change here then select the apply button and the system will reboot.

Ok.

Hopefully they can be of help as well. Ya, I'd change the RBRs LAN IP address to 192.168.0.1 and range .100 to .200, then this should solve the conflict coming from the VPN since they are usnig 192.168.1.1
I don't have any reserved ip addresses, so this shouldn't be a problem. Is the idea with a reserved IP address almost like giving a static IP address to a specific device, so it doesn't auto-assign and be something different? I don't think I have a specific use case for this but it makes sense.
I'm understanding there are 2 options that may fix my issue.1) change my router IP address
2) change the starting and end addresses using all existing settings
Is there a best practice regarding the 2 options?
If I change the router IP address, I'll still be able to use all IP addresses from 2 to 254.
If I change the starting address to 36 and keep ending as 254, I've reduced total number of available IP addresses by 35.
Option 1 seems better, based on that alone. Is there anything else I'm missing?
Try the suggestion I gave and see if this helps. it should. I would change the router IP address since that will be a and should be a quick fix.
Yes you can use .2. thru .254 if you like after you change the router IP address. If you don't have that many devices, then you can make the pool size smaller and won't effect any thing. Something I've been using for many years since I don't have more than 40 devices, I don't have a need to have a IP address pool size that big and I can have a range for static IP addressed devices as I have cameras, NAS and printers that are static configured.
