We hooked up Internet to a new GSI tower dryer at a grain elevator, and assuming this is the correct manual, it wants ports 22, 23, and 80 forwarded to it.

They have a cellphone app, which apparently goes directly to the dryer, not through some intermediary like a Team Viewer server. So I don't see what firewall rules we could put in. Doesn't this let every hacker, script kiddie, and bot herder in the world try to break into it via SSH, telnet and HTTP? Do these guys move on if the default password has been changed? I would think they would run dictionary attacks against it.
