I also tested ping with -M option, from B1 to GW1: ping -M do -s 1448 192.168.20.4
It works up to 1448 bytes, then starting from 1549 I receive the error "From 192.168.100.2 icmp_seq=1 Frag needed and DF set (mtu = 1476)"
And my bat0 configuration is:
bat0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1476 qdisc pfifo_fast state UNKNOWN qlen 1000

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