Running ATC from a laptop using 'create_ap' #315

I'm trying to simulate low network conditions on my real android device based on this answer. I'm using a laptop (x86) with archlinux as a router. In the laptop I have wired enp61s0 and wireless wlp62s0 interfaces. So I created wifi access point using create_ap command, to be specific sudo create_ap wlp62s0 enp61s0 MSI_AP. That thing creates ap0 interface, which I'm connecting my android device to. I specified ap0 as wlan interface in atc and enp61s0 as another one. (enp61s0 is connected to internet)

Unfortunately rules do not work ( I set up up and down speeds to 1kbs, but android's speedtest app shows 20mb/s). Any idea what I'm doing wrong?

create_ap output dump_system_info output log from atc is here

Hi @Deathangel908 it seems you inverted wan and lan. Did you start atcd with something like:

atcd --wan ap0 --lan enp61s0

?

It should be the opposite. e.g

atcd --lan ap0 --wan enp61s0

Thanks for your response. I overrode it in AtcdThriftHandlerTask.py

    DEFAULT_LAN = 'enp61s0'
    DEFAULT_WAN = 'ap0'

So I guess there's no way I messed up with this

well, you LAN is ap0 and WAN is enp61s0. WAN is for the interface that connects to the Internet as in Wide Area Network, not Wireless (A) Network.
