Dear all,

analyzing in deep the problem I have seen that the problem is the checksum: as you can see in my previous .cap file, the packets with data from 192.168.100.2 have a wrong checksum (and my nodes are not using the HW checksum offload function)
Then, I’m starting to investigate how the checksum is calculated. If you have any suggestion or comment, you are welcome!

I could not find anything revealing in the logs you provided. Could you please
follow Sven's suggestion to log both ends as well ?

I could log on every interface; I will do it and send .cap files.
 
Just to not forget the obvious:
* What batman-adv version are you running ?
revision 1439
 
* GW1 routes the packets - does this work via NAT or do you manually add
GW1 routes packets, without NAT
 
routing entries to both ends ?

AFAIK batman-adv has no problem transporting TCP traffic (unless you found an
undiscovered bug nobody has seen before). The most common source of trouble is
the configuration of the setup, in particular MTU settings or routing issues
(which is why most people simply bridge).

I understand your point about batman-adv; also for me, among batman nodes everything works fine.
I will also test the system with bridge on GW
