The above code is a code Ive used to forward traffic in linux.
Now I need to do the same thing in Mac OSX. 10.8 if it matters.
So, here is the deal.
Before, I was using a proxy to connect to the linux machine and using that proxy I was able to monitor traffic using mitmproxy
Now, on the mac, Im using the built in internet sharing and want to use mitmproxy which only listens to stuff from port 8080.
bridge0: flags=8863<UP,BROADCAST,SMART,RUNNING,SIMPLEX,MULTICAST> mtu 1500
ether ac:de:48:81:1d:4a
inet 192.168.2.1 netmask 0xffffff00 broadcast 192.168.2.255
Configuration:
priority 0 hellotime 0 fwddelay 0 maxage 0
ipfilter disabled flags 0x2
member: en0 flags=3<LEARNING,DISCOVER>
port 5 priority 0 path cost 0
The above is the "shared connection" that I need to forward I believe.
