NAT Loopback not working for wired LAN connections #913

Closed GoogleCodeExporter closed 9 years ago

GoogleCodeExporter commented 9 years ago 
What steps will reproduce the problem?
1. NAT Loopback enabled
2. Hardware NAT acceleration enabled for both LAN and WLAN connections
2. DDNS enabled
3. Port forwarding enabled

What version of the product are you using? On what operating system?

3.4.3.6-064-micro

Please describe the problem as detailed as it's possible:

Port forwarding works on the internal network; however, when accessing 
forwarded ports from a wired connection, only local IP addresses work (ex: 
192.168.1.100:6060). However, when using a wireless connection on the same 
network, local connections AND DDNS port forwarded connections work correctly 
(either 192.168.1.100:6060 or dyndns,com:6060).

problem.
