Hello everyone I am trying to configure OSPF between mikrotik routers with ROS 7.14.3 through sstp tunnels, softether VPN is used as a server in the debian 11 operating system (softether secure nat is disabled), the problem is that the ospf neighbor list is empty, multicast packets arrive on the sstp interfaces of both routers (checked using a packet sniffer), on both on routers, firewall rules have been added: . if, with the same ospf instace configuration, I connect 2 routers with an ethernet cable, create an interface template for this connection with the broadcast type, then everything works, I also looked at the packets on the ethernet interface with a sniffer, I see the same multicast packets as on the sstp interface. What could be the problem?
