Sophos utm port for HTTP


What is the port sophos utm listening for HTTP?

Where to make changes to block http file extensions if i am getting the file extensions with help of curl?

I need to block txt,ps files and allow html.

I have setup - HTTP server - UTM -- Http client.

HTTP server

/utm# python -m http.server 8080 --bind
Serving HTTP on port 8080 ...

HTTP client

/etc# curl
html testing

Any help will be really appreciated.
