Looks like I am doing something wrong:
root at andoria # iptables -t nat -A PREROUTING -p tcp --dport 8080 -j
DNAT --to-destination 192.168.114.100:80
root at andoria # telnet localhost 8080
telnet: connect to address 127.0.0.1: Connection refused
telnet: Unable to connect to remote host: Connection refused
root at andoria # telnet 192.168.114.100 80
Connected to a.xx.com (192.168.114.100).
Escape character is '^]'.
iptables -t nat -L
Chain PREROUTING (policy ACCEPT)
target prot opt source destination
DNAT tcp -- anywhere anywhere tcp
Is there anything else I should be doing?
