I've now installed Mageia 3 on two machines on the home network -- and very smoothly it all went. Until I've hit the buffers with shorewall. Setting up permitted services via the Mageia Control Center has no effect. I tick the services I need, I click on OK, I get the confirmatory screen showing what got enabled and I click on OK again. But instead of asking me which interfacess are to be protected, it throws me right back to the Security page of MCC (or to the command line prompt if I just run drakfirewall instead of going through MCC.
All the supposedly enabled services (ssh, nfs, http, ping) remain stubborny disabled. And, indeed, atrying to configure shorewall again brings up the list of services to enable with none of them ticked.
Help! This is a complete show-stopper for me!
