The situation is that the Windows computer can access the Linux computer via this network (via ssh). The Linux system, otoh, cannot access the Windows computer.
What does "access the Windows" mean? How exactly are you accessing Windows? Are bond modes the same on Windows and Linux? ...
The mode (active-backup) is curious. I have tried others (e.g. balance-alb) to no effect.
Active-backup means that only one link is active. If Windows sends packets to a different link, they are lost. Where Windows sends packets is determined by Windows. It is entirely possible that Windows selects different links for outgoing ssh packets and replies to incoming requests. You did not describe how the Windows side is configured. I once spent several days chasing connectivity issues (and it took quite some time to realize there *were* connectivity issues, and not some higher level problems). It turned out two sides of a static aggregate did not agree on which links were active.
