How do I put the exede modem/wifi combo router into pure modem mode? i have a extremely expensive router of my own which is a asus and it cant connect to its DDNS server, im trying to share my mounted harddrive with the internet but cant due to and ip confliction as well because the exede modem/router is a router as well? Double Nat environment is the problem maybe? but can the exede router be put into pure modem mode? is this possible? thanks.
