Background Info
I have rooted an android phone and installed droidwall to get access to iptables. The kernel version is 2.6.35.7-perf.
Objective
Test the efficiency of a proxy (on port 8080) from a comparison of the traffic flow with and without the proxy.
Method
I have creating a test website on a single IP address. I am using an application that monitors how many packets/bytes have been transmitted and recieved by the phone.
Problem
Due to unknown background traffic, unwanted packets are being sent and recieved.
Solution
Use iptables to only allow a connection to one website so I can properly monitor the traffic.
I am able to limit the connections soley to my desired website without the proxy with the rules from here.
In another test, I can move the unrestricted traffic through the proxy with these iptable rules:
iptables -t nat -A OUTPUT -p tcp --dport 80 -j ACCEPT -m owner --uid-owner root
iptables -t nat -A OUTPUT -p tcp --dport 80 -j REDIRECT --to-port 8080
How could I integrate the two sets of rules to redirect the traffic from 1.2.3.4 (example) to port 8080 AND drop everything else.
