Cfrgtkky

I'm trying to set up a Traefik to redirect Hostnames to ports on a server in my company network with several applications.

When I try to access the reverse proxy on port 80 with the host name "evolution" (DNS redirects evolution to 192.168.XX.XX), I can't reach Traefik (nothing on logs).

If I try the same thing directly on server hosting Traefik, I can reach Traefik (logs show my connection and redirection).

Thanks for you help, find more details below.

Examples with curl :

From my machine away on the server :

curl -v evolution.example.com

* Rebuilt URL to: evolution.example.com/

* timeout on name lookup is not supported

*   Trying 192.168.33.33...

* connect to 192.168.33.33 port 80 failed: Timed out

* Failed to connect to evolution.example.com port 80: Timed out

* Closing connection 0

curl: (7) Failed to connect to evolution.example.com port 80: Timed out

From the server :

curl -v evolution.example.com

* Rebuilt URL to: evolution.example.com/

*   Trying 127.0.0.1...

* TCP_NODELAY set

* Connected to evolution.example.com (127.0.0.1) port 80 (#0)
