Hi i have everything setting up on a pi 4, but having troubles setting up the input and the output network ips, how should i do the dhcp ips
I had the same confusion, but the below worked for me.  This is for using Keexybox as primary entry point for all devices (DNS/DHCP/Gateway).

1) set Input network to different subnet then your primary router.
      ex. Router IP is 192.168.1.1
             interface eth0 (for both input and output)
             input to 192.168.2.254
             output to 192.168.1.254
Hi,

Let's say that your router has the IP 192.168.1.1/24 and it is a DNS server. Here is an example of configuration for your KeexyBox:

Input network (network that will reach your devices)
- Interface: eth0
- IP address: 192.168.2.254
- Netmask: 255.255.255.0

Output network (network that will reach your router)
- Interface: eth0
- IP address: 192.168.1.254
- Netmask: 255.255.255.0

DNS and Gateway
- Gateway: 192.168.1.1
- DNS 1: 192.168.1.1
- DNS 2: (Leave blank)

It is also recommended to disable DHCP on the router and enable it on Keexybox. Here is an example of DHCP configuration for your KeexyBox:

Address range for the network: 192.168.2.0/24
 - Enable DHCP (checked)
 - DHCP start IP: 192.168.2.151
 - DHCP end IP: 192.168.2.201

Address range for the network: 192.168.1.0/24
 - Enable DHCP (checked)
 - DHCP start IP: 192.168.1.151
 - DHCP end IP: 192.168.1.201

Reboot Keexybox when you are done.

I hope this will help.
