on which port number WDS server will listen & service when installing on server which is also DHCP server?

hi frineds

in documents we read when we install WDS on the server which is also DHCP server, we must select this check mark :

"do not listen on port 67"

it means we instruct the WDS service not to listen on port UDP 67  to avoid a port conflict between WDS server service and DHCP server service.
So now on which port number WDS server will listen & service ?

thanks in advance
