I just went through the setup for dd-wrt, and it wasn't working, so I wanted to see if possibly this is why: to provide internet to my router, i set the wireless mode to "client" and use the wifi tether option on my cell phone. (this is my only option, i don't have wired internet service where i live). i tried changing tun0 to tun1 in the iptables settings, no effect, and double checked all my settings it's a d-link dir-835, running build v3.0-r30949 std (12/15/16) thanks for any help
