 If you want to test the solution with OAuth proxy, you can try to adapt the following commands (considering `192.168.2.103` is your local IP address):
 
 ```bash
+export IP=192.168.2.103
+
 # In a shell, start BasicOID
-RUST_LOG=debug cargo run -- -s storage -w "http://192.168.2.103.nip.io:8000"
+RUST_LOG=debug cargo run -- -s storage -w "http://$IP.nip.io:8000"
 
 # In another shell, run OAuth proxy
-docker run --rm -p 4180:4180 quay.io/oauth2-proxy/oauth2-proxy:latest --provider=oidc --email-domain=* --client-id=oauthproxy --client-secret=secretoauth --cookie-secret=SECRETCOOKIE1234 --oidc-issuer-url=http://192.168.2.103.nip.io:8000 --http-address 0.0.0.0:4180  --upstream http://192.168.2.103 --redirect-url http://192.168.2.103:4180/oauth2/callback --cookie-secure=false
