DNS Rebind Protection

If you are having troubles accessing http://localtest.me, check if your router does DNS rebind protection. There are various options to avoid this problem.

Add Exception

You can add an exception for the following domains in your routers configuration:

bar.localtest.me
foo.localtest.me
keycloak.localtest.me

For instructions see your router vendors documentation. For example:

• AVM FRITZ!Box
• Google Nest

Use external DNS

Use an external DNS service. For example:

• Cloudflare
• Google

Add to /etc/hosts

Add this to your /etc/hosts:

127.0.0.1 bar.localtest.me
127.0.0.1 foo.localtest.me
127.0.0.1 keycloak.localtest.me
