Re: Forward specific port to another ip

[Andy Lego <legoandy@gmail.com>]

Hi Edmundo,

Looks like I am doing something wrong:

root@andoria # iptables -t nat -A PREROUTING -p tcp --dport 8080 -j
DNAT --to-destination 192.168.114.100:80
root@andoria # telnet localhost 8080
Trying 127.0.0.1...
telnet: connect to address 127.0.0.1: Connection refused
telnet: Unable to connect to remote host: Connection refused
root@andoria # telnet 192.168.114.100 80
Trying 192.168.114.100...
Connected to a.xx.com (192.168.114.100).
Escape character is '^]'.
^]
telnet> close
Connection closed.

iptables -t nat -L                                                    
                                                 ~
Chain PREROUTING (policy ACCEPT)
target     prot opt source               destination
DNAT       tcp  --  anywhere             anywhere            tcp
dpt:webcache to:192.168.114.100:80

Is there anything else I should be doing?

Thank you.

Andy
