I am using MariaDB 10.2
I have node2 (2.2.2.2) running as a slave to some external database. I bootstrapped node2 as the first member of a Galera cluster "my_cluster".
Node1 (1.1.1.1) joined with rsync SST but after an hour I see that it's behind node2.
I tried running some inserts manually and it works both ways.
However anything added by the replication to node2 in completely ignored by node1.
node1:

Your node2 needs to have
log-slave-updates=1.See also SeveralNines' article on the topic which states:
