To anyone who can help:
I have an ER-8 (firmware version 1.9.0, also tried 1.8.5) installed and up and running in a simple home setup. The owner has many camera's and other internal devices he accesses remotely. I have setup port forwards for the devices, and they all work fine, however they do not work internally. I have setup Dynamic DNS since his public IP changes, and this is what he is how his remote devices find his home network. When these remote devices are on site, they fail to work. For instance I do have a camera server internal, when I access via the Dynamic DNS name and port, it fails to load. When I access remotely the same way, the login page pops up immediately, when I try internally using internal IP and port, it works fine as well. I CAN ping the Dynamic DNS host name and it responds with the public interface IP.
I have only setup port forwards for devices, and checkmarked the Hairpin NAT feature hoping that checkmark would correct the issue, but sadly it doesn't. I have will post the config here. Please help, thanks! Also I realize bridging the eth1 and 2 is stupid, but it's all working and I don't wan to to break anything, this is low volume as far as data is concerned.
Also, I am not nearly as familiar with the CLI but I will do my best, GUI would be great. Thank you!
