You wrote :
"I open port 5555 on the router and forward it to wlan0 (192.168.1.71)"

So I assumed that the connections would arrive at the Linux box on port
5555 :
"If the router redirects port 5555 to 192.168.1.71 without changing
the destination port"

But obviously they arrive on port 80, so you can ignore my rule and just
use the one you proposed :

iptables -t nat -A PREROUTING -i wlan0 -d 192.168.1.71 -p tcp --dport
80 -j DNAT --to 192.168.70.140

And make sure ip_forward is enabled.

No, unless you also have filtering rules.
