wireless mode=station

Fri Feb 09, 2018 12:35 am

I have a wireless interface (WLAN below) with mode=station connected to a wifi (AP below).
AP works properly (many other clients work without any problems)
WLAN is getting an IP from DHCP
Ping from AP (192.168.12.1) to WLAN (192.168.12.254) works fine. The same for ping from WLAN to AP.
I can't route any traffic from WLAN to AP:
Code: Select all
/ping address=8.8.8.8 interface=WLAN

    sent=20 received=0 packet-loss=100%
Pinging 8.8.8.8 from other clients connected to the AP works fine.
Any suggestions what's wrong?

Masquerade is for forwarded traffic, not for outgoing, cause src-ip is fine. Anyway it is set.
I see ping packets don't reach AP interface, nothing here:
Code: Select all
/ip firewall raw
add action=passthrough chain=prerouting in-interface=AP log=yes

Have you ensured that the default route has been added?
/ip route print
You should see a route for 0.0.0.0/0 to your gateway, if not make sure you've enabled add-default-route for your dhcp client

The default gateway is and will be eth1.
I want to route just specified connections through WLAN.
In routes I have:
Code: Select all
 #      DST-ADDRESS        PREF-SRC        GATEWAY            DISTANCE
 3 ADC  192.168.12.0/24    192.168.12.254  WLAN                       0
But the problem is at much earlier stage.
I connected WLAN to AP and I'm trying to ping 8.8.8.8 from the WLAN router itself. Without any masquerade/routing/whatever connected clients. I know how to do it, it's not the case.
The problem is that pinging WLAN (192.168.12.254) -> (192.168.12.1) AP (PUBLIC_IP) -> 8.8.8.8 does not work.
Any other client connected to AP can ping 8.8.8.8 and make any connections they want, so I guess the problem is with WLAN, not with AP.
As I wrote above I'm trying to ping with:
Code: Select all
/ping address=8.8.8.8 interface=WLAN
to output ping packets on appropriate interface

Any traffic you wish to send over the WLAN will need a route, if you add a static route for 8.8.8.8 with a gateway of 192.168.12.1 it will work, it is not enough to simply specify an interface for your ping.
