MMI 3GP with TP-Link PPP - Google & TMC working but no WAN on WIFI Hotspot

Hi Guys,

sorry for writing in english, my russian is very poor... First I want to say that this forum is top of information about audi mods. Don't even find those informations in germany. Great!

I did on my a6 4g 12/2011 the online-connection over the USBtoEthernet-Solution; works nice with google, audi connect and Traffic online. I Also can connect to the WIFI-Hotspot, ping the gateway and even ping e.g. 8.8.8.8, but no dns. Services like http are not working (behaviour like you put a client in a wrong subnet).
The Acces point dont use the PPP or do i have to do a route to the tp-Link WAN? This is my conf:

WIFI Access Point:
---
uap0: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> mtu 1500
