networking - DVR port forwarding won't work

I have a DVR device and I like to watch the cameras from outside of my house, I tried to use port forwarding to do that but although I forwarded the ports I couldn't watch the cameras.

In my DVR's menu there is this options:

HTTP Port: 80
Server Port: 8670
Mobile Port: 101
DHCP : checked
IP Address: 192.168.1.34

and in my router's port forwarding menu I've added this ports:

when I'm connected to the router with wireless if I write 192.168.1.34 in my browser nothing appears, but when I'm connected with a LAN cable the DVR menu is shown . I'm confused! what is wrong?
