This sounds sensible, you just have to make sure that this is the
right host.

I *think* I’ve heard of them before and “Historical Materialism” is
definitely a household name to me :)

I don’t know your router and thus cannot comment on this.

No, that is correct.

I wonder why you get @historicalmaterialism.info. I would have
assumed that, after your router forwarded the connection to your
specific host it would be @engels.historicalmaterialism.info or
something.

Do you use NAT or something similiar in your network?

I don’t know. This *somehow* looks as if you are trying to connect to
the host historicalmaterialism.info, which just doesn’t sound right
if you don’t have a host of that name.
