I was sure, I double some configs not necessary to double. :-)
But: it was my first configuration. It ran halfways. I could ping
from one gateway to the other, but not from one subnet to the other.

This is true for this config either. I can ping from gateway to
gateway, but I can't ping from gateway to any other host than the
gateway on the remote side. Same for any local host: none of them
can reach any remote connected host. It just doesn't work. No
additional route setup, no sourcerouting, no nothing. In short: I
can connect the gateways, but not the networks.

That is what I've read. Adding (left|right)sourceip= again made the
connection gateway/gateway work, but not any of the other hosts are
reachable. I could connect two hosts, but not two networks.
Removing the gateway/network network/gateway and gateway/gateway
configs doesn't change anything: I can ping from gateway to gateway,
but not from network to gateway or network to network.
