 The tool is necessary due to [#7332](https://github.com/kubernetes/minikube/issues/7332).
 
+#### Setup cntlm proxy
+
+Follow these steps if you are behind a firewall and have only access to the internet from behind an authenticating corporate NTLM http proxy.
+
+```bash
+$ brew install cntlm
+```
+
+Locate and edit the config file to set your proxy and authentication credentials ( `vi ~/.brew/etc/cntlm.conf` )
+```
+Username        your_userid
+Domain          your_domain
+Password        your_ntlm_proxy_password
+Proxy           your.corporate.proxy.host:8080
+# include domain .tx.test and minikube ip address
+NoProxy         localhost, 127.0.0.1, 192.168.49.2, *.tx.test, *.other.domains
+Listen          3128
+```
+
+(Re-)start cntlm
+```
+$ pkill -x 'cntlm'
+$ cntlm
+```
+
+Locate and edit the settings file for your shell to set env vars ( `vi ~/.zshrc` )
+```
+export http_proxy=http://localhost:3128
+export https_proxy=http://localhost:3128
+# include domain .tx.test and minikube ip address
+export no_proxy=localhost,127.0.0.1,192.168.49.2,.tx.test,.other.domains
+```
+
+Save and apply your settings and test internet access
+```
+$ source ~/.zshrc
+$ curl https://github.com/ -Is | grep server
+server: GitHub.com
+```

 ### Network Setup on Windows/wsl2 with NTLM-proxy
 
 Configure wsl networking, assign additional fixed IP addresses to both wsl2 and windows, the wsl2-ip-address will then be used as cluster-ip-address. Do **not** use 127.0.0.1 as Cluster IP, as this causes issues when services try to access other services via the ingress from within the cluster.
