How do I access RHN (yum/up2date/satellite-sync) through a firewall?

For up2date, yum, rhn_register, and satellite-sync to work correctly, your firewall must allow connections to:
- rhn.redhat.com on port 80 (http)
- rhn.redhat.com on port 443 (https)
- xmlrpc.rhn.redhat.com on port 80 (http)
- xmlrpc.rhn.redhat.com on port 443 (https)
- content-xmlrpc.rhn.redhat.com on port 80 (http)
- content-xmlrpc.rhn.redhat.com on port 443 (https)
- content-web.rhn.redhat.com on port 80 (http)
- content-web.rhn.redhat.com on port 443 (https)
- cdn.redhat.com on port 80 (http)
- cdn.redhat.com on port 443 (http)
RHN Satellite needs additional access to:
- satellite.rhn.redhat.com on port 443 (https)
- satellite.rhn.redhat.com on port 80 (http)
- content-satellite.rhn.redhat.com on port 80 (http)
- content-satellite.rhn.redhat.com on port 443 (https)
IP addresses for servers are not permanent. Please use the domain names instead ; this is partly because we distribute them through Akamai
It’s necessary to allow the following ports/hostnames on firewall to have fully working yum
- .akamaiedge.net on port 443 [https]
If you can’t open your network and use RHN classic you can disable location aware updates as a workaround. This will not work with RHSM.
For systems using RHSM, please see Configuring my firewall to access RHSM.
