OSPF over SSTP

[RedCat]

Hello everybody! I'm trying to configure OSPF between mikrotik routers via sstp tunnels, softether VPN is used as a server on the debian 11 operating system (softether secure nat is disabled), the problem is that it seems like ospf packets are sent between the routers, but on the routers themselves in the list of neighbors ospf is empty, but if I try to use mikrotik as a server, with the same interface settings, then neighbors appear, can the softether VPN server somehow influence this?

FilterOSPF is ON? https://www.softether.org/4-docs/1-manu ... irtual_Hub
If not, try L2 instead of SSTP.

The OSPF filter is disabled, packets are reaching the router interface (checked with a packet sniffer), the question was whether the softether server could interfere with the contents of the packet?
