Force DNS to any client on your network

Enforce any client that uses port 53 for a DNS lookup to get redirected to the DNS server of your choice. This effectively forces any client with custom or self-configured DNS to still go through your DNS server of choice.

UI Settings

Navigate to the UI and then to: Firewall/NAT -> NAT. Click on "Add a Destination NAT Rule". In my case eth1 is the port all clients go and eth0 is where the WAN goes in, and 192.168.0.1 is the router itself where the DNS server is

• Inbound interface: eth1
• Translations Address: 192.168.0.1

Remote Kubernetes using SSH

My setup is using a Macmini with Docker for Desktop installed and with the Kubernetes option enabled. The main objective of the setup: use kubectl directly without any additional flags from my local computer, accessing/interacting the remote k8s instance

Ensure SSH is setup with key-based authentication

Copy public key to the remote authorized_keys file

cat ~/.ssh/id_rsa.pub | ssh admin@macmini-server 'umask 0077; mkdir -p .ssh; cat >> .ssh/authorized_keys'

#   AssertionError: Could not find "cmake" executable!
brew install cmake

# and then install protobuf which fixes:
# CMake Error at CMakeLists.txt:292 (message):
#    Protobuf compiler not found
#  Call Stack (most recent call first):
#    CMakeLists.txt:323 (relative_protobuf_generate_cpp)
