Hello,
To answer your first question about the DNS redirector, you have the explanation in this thread https://forum.keexybox.org/Thread-DNS-Se...d=98#pid98
DHCP config will depend on how you want to use keexybox for your PCs:
If PCs have to use keexybox as DNS only, you can enable DHCP only for external network. So the network range IP for PC will be 192.168.1.201 to 251 that will get as DNS server 192.168.1.1 (keexybox) and as gateway 192.168.1.254 (your router).
If PCs have to use keexybox as DNS and gateway (needed to use Tor), range have to be enabled in both network because you are using the same interface (the internal interface is a virtual interface of external interface). So the network range IP for PC will be 192.168.0.1 to 100 that will get as DNS server 192.168.0.254 (keexybox) and as gateway 192.168.0.254 (keexybox). Even if you do not use external ip range, it must be defined, if not, DHCP can't start.
In this configuration, you can do DHCP reservation (optional) for some PCs on external network by declaring them as device and set an IP for each 192.168.1.X. In this configuration, these PCs will get DNS server 192.168.1.1 (keexybox) and as gateway 192.168.1.254 (your router).
PC can't resolve any domain ?
Keexybox block everything by default. You must have a user account on Keexybox to use on the captive portal from the PC or else declare the PC as a device and connect it when declared.
If you do not want create users and declaring device and want to enable the DNS/Internet for the whole network, you must go to "Captive portal", set "Internet access conditions" to "None" and assign a profile.
