Network Access Hub reserved IP addresses.

I just upgraded from the 1 to 3Gbps internet plan due to the black Friday deals and my existing discount terms going away. The Telus technician replaced the Actiontec T3200/Alcatel-Lucent ONT equipment with an Arcadyan NH20A Network access hub and a Boost Wifi 6 garbage can. I'm now in the process of reassigning my internal LAN IP addresses to match my previous configurations (via Network > LAN > LAN DHCP (add)). The only existing DHCP reservation listed is the Boost wifi device. I am unable to assign many of my devices back to their previous IP addresses with the following message (The IP address 192.168.1.21 to 192.168.1.63 has been reserved.) 

Does anyone know where in the NAH GUI I can find the settings to remove this reservation? I have quite a few devices that I would like to assign to this range. I'm unsure how many existing configurations will be broken with them being changed.

I did put in a call to Telus Technical Support. I had a hard time getting them to understand my issue was with settings for internal static IP addresses, not my external IP address (I think 90% of their calls are from residential customers that don't know the static IP abilities Telus restricts to Commercial plans). I was told their tier 1 training is based around their external network setup, tier 2 is reserved for back-end network issues and there is no one that can direct or discuss device-level things like this. I'm disappointed as this is a Telus device with Telus firmware, they are likely the only ones with reasonable control or knowledge of how it is set up. I feel my solution may be to purchase my own 3Gbps capable router, bridge this thing and just have to live with having another node in my network chain slowing things down.

Normally the Telus gateways tend to start dynamic LAN IPs at .1.64 and go up from there. It's possible the T3200 was more forgiving and would let you set static IPs below that. If the restriction is baked in to the firmware, you may have to try settings static IPs above .1.64.  Tech support won't have a way to override the reservation if it is baked in. Technical support has a narrow scope of support for the more advanced features.

Thank you for the straightforward answer. I was just hoping that was the case. It's too bad their support personnel don't understand even enough so they can let me know. Is it possible to disable LAN DHCP so I can implement a separate DHCP service without conflict? I do not see that option anywhere either. Would enabling Bridge on the NAH work for this?

As far as I know, none of the Telus gateways can have DHCP disabled. If you bridge the NAH and connect your own router to the 10G LAN port, then you connect whatever router you want. One thing I did in the past was connect a router to an unbridged T3200M and just used that. It did create double NAT but for what I was doing at the time, it worked just fine.
