Through the bridge. I can't tell what's missing until you show us your
bridge configuration, if you have any. I'll show my config for
comparison:
OK. Now

If you use -net user you get a NAT-based solution (you then need to
punch inbound holes using the hostfwd parameter, as necessary). This
solution also requires no root priviledge, so it's an easy win.

I think this setup might need additional configuration on the outside,
because you need to add the same subnet route on your Internet
modem/router. I don't think qemu gives you NAT for free...

You're adding a host route, whereas you need a network route. Try:

You need to add a 'bridge_ports' line to indicate that the interface
