I currently have my openwrt router setup 'behind' my fios actiontec router. I am trying to get OpenVPN and having issues. I'm wondering if putting the openwrt router in the DMZ on the fios router would be a good idea? I seem some references to 'double NATing' which I think I now doing. If I put the openwrt router in the DMZ is there any configuration I need to change to make sure it's not 'double NATing'. Basically I'd like to just treat the fios actiontec router as a modem in this case and send all traffic to the openwrt router.
