Ability to disable rebind attack prevention?

[Cheezykins]

This feature is driving me nuts.

I run my own DNS server which has its own rebind attack prevention, but also overrides some public DNS for internal things here at home.

I can't configure the router to issue my own IPs for DNS servers via DHCP, so as far as I can see I either have to also run my own DHCP server with all of the overhead that comes with it, or stick with the router and rely on the router's built in DNS server to forward to my internal one.

But in that case, my internal lookups to my overrides fail due to this non-configurable rebind attack protection, which is completely unecessary!

I desperately need either a way to configure the router's DHCP server to issue whatever DNS servers I tell it to, or to disable the rebind prevention on the internal DNS server.

Is there any hope for this?

With more exotic installs, and with the dumbing down of the router, it's often advantageous to use your own router.

Yeah but that's like £200+ for a compatible one, this shouldn't be so difficult for something as "exotic" (read, fundamentally basic) as DNS or DHCP configuration.

The additional overhead from running DHCP on your server should be pretty minimal - DHCP, just like DNS is not usually a CPU hog!  When it comes to exotic, that is pretty much anything that the average user is not going to be doing!  Pi-Hole for example is perfectly happy running on a Pi-Zero even with the DHCP function in use!

I'd echo the comment about PiHole. I have it running in a Pi version 3 serving DNS, DHCP and DNS blacklist without any issues.

Ahh you're right, I'm just getting frustrated wiith it, I'll have a fiddle with dnsmasq tomorrow evening, probably not a good idea to potentially (temporarily) trash my home network right before bed!

Personally, I try to take a light touch regards DHCP, so I only have one device with a manual IP address (set on the device), everything else I may need to access can be accessed via a hostname (again set on the device, not the router).
