If you login to the web interface of the NVR, there should be a screen that shows you a list of all of your cameras with an Internet Explorer icon to the right of each one. If you click on one of the IE icons, it should connect you to the web interface of that camera.
That's weird, it should try to open 192.168.1.108:[port#], but the [port#] will be unique and different from what's shown in that list.
If the camera isn't Dahua, or is Dahua running hacked Chinese firmware (many models with "C" in the name are), it might not work, ... but I'd still expect it to try to access 192.168.1.108:[port#], not 10.1.1.x.
Another option (if the PC you're trying to access the cameras from has Ethernet) is to temporarily connect that PC to an ethernet port on the back of the NVR. That should put the PC on the 10.1.1.x network and then it should be able to directly access the cameras.
