Bothered about failing Shield Up due to Port 113 reported as Closed? For most routers, it seems that simply port-forwarding all Port 113 traffic to an out-of-range IP address is sufficent to stealth Port 113. That's not enough for this router. Two steps are required: - Port-forward all Port 113 traffic to 192.168.0.250 (that's what I used), and; - Also define 192.168.0.250 as DMZ. That'll pass Shields Up for the EBR-2310 Router. Hope this helps!
