below is my iptable rules:

  :PREROUTING ACCEPT [2:230]
  :INPUT ACCEPT [2:230]
  :OUTPUT ACCEPT [3:370]
  :POSTROUTING ACCEPT [0:0]
  -A PREROUTING -s 10.13.0.0/16 ! -d xx.xx.xx.xx/32 -j ACCEPT
  -A PREROUTING -p tcp -m tcp --dport 80 -j DNAT --to-destination :8080
  -A PREROUTING -p tcp -m tcp --dport 443 -j DNAT --to-destination :8443
  -A PREROUTING -p tcp -m tcp --dport 843 -j DNAT --to-destination :8843
  -A POSTROUTING -s xx.xx.xx.xx/32 -j ACCEPT
  -A POSTROUTING -s 10.13.0.0/16 -j MASQUERADE

  net.ipv4.ip_nonlocal_bind = 1
  net.ipv4.conf.default.rp_filter = 1

Stop your iptables service and Selinux should be disabled. service iptables stop Vi etc/selinux/config selinux=disabled
