Normally to NAT traffic coming in you have to NAT the responses back to
the right places, but it gets tricky very quickly so someone created
MASQUERADE to unwind all NAT bindings automatically on response packets.

I'm not sure about speed, but its easy to configure.

Weird, I'd expect a list same as for the -t nat you gave earlier, but
never mind. I thought maybe there was a forwarding rule or policy
blocking things. Since MASQUERADE fixed it, we don't need to look any
further.
