Hello, I can't route my IPs into a OVH server, can you help me to find the problem?


Mikrotik GRE IP: 192.168.55.10

OVH Server GRE IP: 192.168.55.20

GRE iface name: ali1_fr1-ovz1 IP to route from Mikrotik to OVH Server: 185.47.128.50 (I want use this IP in a VZ container)


Ping from Mikrotik to OVH GRE IP -> GRE OK



ping 192.168.55.20
