[ubuntu-in] proxyless internet connection sharing

[Pritam Baral]

On similar lines, I have set-up transparent proxy so that devices
connecting to my WiFi do not need to set-up proxy on their own (but will
still work if they do.) Note however, that this is an Infrastructure
Wireless network I created (much like what Connectify does on Windows.)

I have used a modified set of iptables rules for sharing internet over
Ad-Hoc WiFi network, but haven't updated it on the blog. However, here are
the commands:

sudo iptables -t nat -A PREROUTING -i wlan0 -p tcp -m tcp --dport 80 -j
DNAT --to-destination 10.42.0.1:5123
sudo iptables -t nat -A PREROUTING -i wlan0 -p tcp -m tcp --dport 443 -j
DNAT --to-destination 10.4.0.1:5124

*NB: 10.42.0.1 is the local Wireless interface address under Ad-Hoc as
created by NetWorkManager. 192.168.0.1 is the address if you follow my
previous blog posts on creating Infrastructure Wireless APs*

please note that *iptables-restore* washes away previous rules, but the two
commands above only add to iptables, not replace them (much like the
difference between > and >> in bash redirection)
