set the parameter on the kernel
sysctl -w net.ipv4.conf.all.route_localnet=1

Adding the firewall rules
firewall-cmd --add-masquerade --perm
firewall-cmd --direct --add-rule ipv4 nat OUTPUT 0 -d 127.0.0.1 -p tcp --dport 8443 -j DNAT --to-destination 192.168.1.6:8443
You can check the redirected rule like this
firewall-cmd --direct --get-all-rules
You can remove it by running the following command
firewall-cmd --direct --remove-rule ipv4 nat OUTPUT 0 -d 127.0.0.1 -p tcp --dport 8443 -j DNAT --to-destination 192.168.1.6:8443
