Hot to remove the port number 8080 from my ALM URL?

We have upgraded from HP 9.2 tp ALM 11.52.

We were useing the ipaddress of application server temporarily to access the ALM.

Now, we have moved the DNS name - eg - qualitycenter.domain.com to the ipaddress of new applicqation server.

After that, i am able to access the ALM by using - qualitycenter.domain.com:8080/qcbin

I have not done any configuration in IIS or apache. How do i get rid of the port number from the URL.

I also tried opening the port 8080 from firewall settings, but no use.

Quick help would be appreciated.
