title: Configure route on Synology NAS with iptables
body: <p>I have a Synology NAS and I want configure routing on it: nat with port forwarding.
  Googled I found that it is possible with iptables, but I didn't found web interface for it.</p>
  
  <p>So, my question is do you know how to configure nat with port forwarding on DSM 5.0 with web interface and is it possible?
  Thanks!</p>
