It sounds as if you've accidentally installed a Desktop Environment
as your new firewall system, which does sound rather inappropriate.
Perhaps the easiest way of backing out of this so early in the
system's life is just to repeat the installation as an expert install
and avoid making that mistake again (at "Software Selection").
Obviously the partitioning stays the same, but you just reformat the
same partition layout.
BTW ifconfig is in net-tools nowadays, if you prefer that to ip.
