Ok, thank you for the answer, yes, we have note that we need to add a frontend and backend in haproxy to allow the access to mds. Otherwise, we test another architecture, more simple to understand who cpeh works at this level), replacing the haproxy with a simple gateway. Now the clients contact with MON and MDS through this gateway and we see two behaviors: 1- The clients cephfs access only works if we route all OSD traffic through gateway with first public networks. 2- If we don't route this traffic because we suppose that the cepfs client connect with the OSD directly through the second public network ( the OSD have access to this second public network) mount action doesn't work, why?, It looks like the client only try to connect with OSD through the first public network and not through the second. Our question is how ceph warn to cephfs client to use this second public network? Thank you again!!
