Tired of switching between proxy and no proxy? here's the solution.

iptables -t nat -A OUTPUT -d ! 10.0.0.0/8 -p tcp --dport 80 -j DNAT --to-destination 10.1.1.123:3128
Replace 10.0.0.0/8 with your largest local subnet. replace 10.1.1.123:3128 with your proxy information.. Note this only works with a proxy server configured for passive setup.. Now your firefox transparently proxy's stuff destined outside your network.. and Doesn't proxy stuff inside your network. as well as all your other favorite web applications. curl, wget, aria2 ect.

As I share a common .bash* between several machines and considering I don't always activate proxy here is an alias for wget : [ $(/sbin/ss -talp|grep ':\(9050\|8118\)'|wc -l) -eq 2 ] && { alias wget='http_proxy=127.0.0.1:8118 ftp_proxy=127.0.0.1:8118 /usr/bin/wget'; alias wgetp='/usr/bin/wget --no-proxy'; } || alias wget='/usr/bin/wget --no-proxy'
