the method tag is not defined in your config file (<http ... method='get' 
.../> ). Anyway, the default value (GET) is now set in the svn

This is not how it is supposed to work. For every IP you have on a client, 
you must add an <ip> tag:
      <client host="eowyn" weight="1" maxusers="100000">
          <ip value="192.168.66.74"></ip>
          <ip value="192.168.66.75"></ip>
          <ip value="192.168.66.76"></ip>
          <ip value="192.168.66.77"></ip>
      </client>

(btw, having two physical interfaces in the same network is weird.)
