If you have a host-based firewall, that's something you (well, the
sysadmin. for the host running DSpace) need to adjust to let these
ports through.  Since you're on Linux, your firewall (if any) will be
'iptables'.  Since you're on Red Hat, they may have put some gooey
thing of their own devising in front of 'iptables', so check your RHEL
documentation for how to adjust your rule set.

If you have a corporate firewall, your network group will need to
adjust it.  How you do that is local to your organization.

It's possible you have both.  There may even be a firewall in the real
box hosting your VM.  (I've never seen that, but I've not seen
everything.)  You need to open the path through all obstacles that may
intervene.

It's the nature of firewalls that the only thing you see if you get it
wrong is nothing.  You just have to keep trying until it's right.  But
it does follow documented rules, so it's possible to know how to get
it right.
