I am facing issues in iptables rules. Requirement is to nat incoming request from server A on port 9443 to 443 of server B. In my scenario., Server A 10.10.8.33 - - iptables configured here. Server B  10.21.2.31 - - web server. I have configured these rules iptables -t nat -A PREROUTING -p tcp --dport 9443 -j DNAT --to-destination10.21.2.31:443iptables -t nat -A POSTROUTING -p tcp -d 10.21.2.31 --dport 9443 -j SNAT --to-source10.10.8.33:9443Which is not working?.I am trying to browse https://10.10.8.33:9443 from my local windows 10 machine C.. IP 10.21.2.93. Elaborating my request... incoming request to server A on 9443 should be NAT to 443 on server B,  and C will be able to get the page. Requesting for help.
