How to forward to the same port in linux?

Question

linux

Guys! I'm talking about port forwarding.
The daemon is running on port 5984. This is a database.
I want to open it from another PC inside the network 192.168.0.102:5984

sudo iptables -t nat -A PREROUTING -p tcp --dport 5984 -j REDIRECT --to-ports 5984

Does not work.
BUT

sudo iptables -t nat -A PREROUTING -p tcp --dport 5983 -j REDIRECT --to-ports 5984

Works

Answer 1

sudo iptables -A INPUT -p tcp --dport 5984 -s 192.168.0.0/24 -j ACCEPT

old rules should be deleted.

Answer 2

It seems to me that you need to dnat (change the destination address) on the PC where the daemon is running.
