There is no such thing as secure\safe on an internet facing machine.
Everything can be hacked given enough time.
A DMZ will provide some security, but if hacked, then your foobarred.
The attacker no longer even requires making inbound connections,
he just makes outbound ones from your DMZ and your owned. Poisoning all
your outbound traffic.
IMO, you would be just as well only forwarding the required ports from
the netgear to the server in your network. And heavily secure those
services.
Selinux would help, severely restrict ssh and other login methods etc etc.
YMMV.
