“MULTI: bad source address from client , packet dropped” or “GET INST BY VIRT: [failed]”?
These errors occur because OpenVPN doesn’t have an internal route for 192.168.100.249. Consequently, it doesn’t know how to route the packet to this machine, so it drops the packet.
Use client-config-dir and create a ccd file for your client containing the iroute option to tell OpenVPN that the 192.168.100.0/24 network is available behind this client.
