Setup IPTables. Now we need to deploy IPTables on Host machine so that we could connect Docker container Apache from outside world. First we should check port 80 on Docker Host machine. #nc -w 5 -v 192.168.43.47 80 nc: connect to 192.168.43.47 port 80 (tcp) failed: No route to host Let’s deploy IPTables for Docker Container IP Address: 172.17.0.3
The port-forward command establishes a tunnel from the target pod to your localhost. The command requires you to define the type or name of the resource as well as local and remote port numbers: kubectl port-forward TYPE/NAME [options] LOCAL_PORT:REMOTE_PORT. If several pods match the type/name criteria, a random one is selected by default. The iptables-persistent looks for the files rules.v4 and rules.v6 under /etc/iptables. These are just a few simple commands you can use with iptables, which is capable of much more. Read on to check on some of the other options available for more advanced control over iptable rules. So after much searching around, I found the answer uses iptables, setting up a NAT, and using the built-ins PREROUTING and OUTPUT. First, you must have port forwarding enabled: INPUT and FORWARD policy DROP, OUTPUT policy ACCEPT. sudo iptables -A PREROUTING -t nat -i ens33 -p tcp --dport 22 -j DNAT --to 192.168.1.2:54045 sudo iptables -A FORWARD -p tcp -d 192.168.1.2 --dport 54045 -j ACCEPT Result: SSH operation timed out. Also tired INPUT and FORWARD policy ACCEPT still operation timed out. 2nd Attempt Aug 19, 2016 · iptables -P INPUT DROP iptables -P FORWARD DROP iptables -P OUTPUT ACCEPT iptables -t nat -A PREROUTING -p tcp -m tcp -i eth0 --dport 80 -j DNAT --to-destination 10.0.10.6 iptables -t nat -A POSTROUTING -o eth0 -j MASQUERADE iptables -A INPUT -i lo -j ACCEPT iptables -A INPUT -m conntrack --ctstate RELATED,ESTABLISHED -j ACCEPT iptables -A INPUT -j REJECT --reject-with icmp-host-prohibited
How to forward ports in DD-WRT & Tomato with iptables
All Known Ports - port forward

It does not redirect the port for clients running on the iptables machine trying to connect to port 25570 (for example). These entries will forward the port for connections coming from the network or from the local host running the services. 2) Add 2 iptables rules to forward a specific TCP port: To rewrite the destination IP of the packet (and back in the reply packet): iptables -A PREROUTING -t nat -p tcp -i ppp0 --dport 8001 -j DNAT --to-destination 192.168.1.200:8080 To rewrite the source IP of the packet to the IP of the gateway (and back in the reply packet):
