Ok, test plan:
* Find the machine and interface were a response from google.com could be
received but which will not forward it to the other interface
* take a real dump on all interfaces (wan and lan)
tcpdump -s 0 -i eth1 -w eth1.dump
* when the response packet is forwarded over the lan/bat0 interface but
doesn't get to the final machine than please also create a tcpdump on the
receiving machine (real interface and maybe bat0)
* Go to your router and check mtu of your wan interface
* Try to ping google.com with the maximum size (mtu - 28 bytes, for example
mtu 1492): ping -M do -s 1464 google.com
* Send small tcp packet with small tcp response:
echo "HEAD / HTTP/1.1\nHost: git.open-mesh.net\n\n"|nc git.open-mesh.net 80
