Hi,
I have a problem to connect to the Internet. We are using Batman advanced 0.2.1 and IPv4 here in oldenburg. Our setup looks like this:
Laptop-[wifi]->Fonera-[wifi]->Dir300-->OpenVPN--> virtual OpenWrt machine-->internet.
The default route of the laptop goes to the virtual OpenWrt machine wich provides an Internet connection.
I can acces google (wget google.de) but not heise.de or golem.de. I´m not verry familar with network configurations but I heared that this might be an mtu problem.
All devices in the network (tap0, ath0, ath1, wifi0) have an mtu of 1524 except bat0 and br-mesh which have an mtu of 1500.
Our routers are configured to bridge connections from non batman devices (like the laptop) to bat0. This is done in the device "br-mesh".
Everythink works fine, except I can´t connect to internet websites that are not google.de.
When I decrease the mtu of the wireless device of the laptop to 1476 everything works fine. But I have to do this by hand and on a client this is bad.
Does anybody know what I´m doing wrong?
Greetings Clemens
