    <div class="moz-cite-prefix">You are right, the router must have an
      interface in external network and the external network must have a
      subnet<br>
      <br>
      How exactly did you try to create subnet? I guess using a CLI
      command?<br>
      It looks like you didn't specify the network which the new subnet
      should belong to.<br>
      <br>
      Try following this doc about creating an external network subnet:<br>

      If you're still getting any errors, look into logs for details:

            </span>What strikes me is the sixth column. It is/should be
            the "Remote Security Group"<br>
            column.<br>
            <br>
            I'm a little unsure on how to use that, but if all those
            rules come from<br>
            the 'default' security group, then you'll probably end up
            with a loop<br>
            or something..<br>
            <br>
            <br>
            But because of the two Any/Any rules, you would not need the
            80/443 rules.<br>
            Nor the 22 one.<br>
            --<br>
            Life sucks and then you die<br>
