Dear Sven, Marek<br><br>you can find as attachment the dump on eth2 of GW (tcpdump -ni eth2 -s 0 -w gw.cap); <br>the output of batctl td -p 4 eth1 is:<br><br>10:29:15.510000 BAT 52:54:00:00:20:01 &gt; 52:54:00:00:30:01: UCAST, ttl 50, IP 192.168.100.2.9001 &gt; 192.168.20.4.45417: TCP, flags [...PA.], length 6<br>

&gt; It is correct. I&#39;m using openwrt and, at the moment, without -M option.<br>
&gt; 1500byte packets work, with fragmentation.<br>
&gt; However, my TCP packets are small (about 60bytes). I have verified TCPDump<br>
&gt; file and packets arrive. It seems that the Linux IP stack does not forward<br>
&gt; them to the application.<br>
&gt; Moreover, if I disable batman on B1-GW1 link, it works<br>
</div>So it would be a good idea to do what Marek said. Give him a dump with `batctl<br>
td` on the gateway and if I could add something: complete tcpdump of both ends<br>
so we can see what packets receive on both sites.<br>
<br>
