I'm struggling with access from WAN to my NAS. I have put NAS to DMZ. Has setup ddns on it. Tried also port forwarding. . As long as I'm into LAN all is working fine. However if I try to access my NAS over WAN than no chance. Any idea what else has to be done on router setup ? Already disabled NAT acceleration but it does not help. Currently has Merlin 3.0.0.4.378.50_0 firmware but it was not working on previous original version as well. Ping is working well. Any idea ?
