And that did work, just how I wanted:
admin@zeroshell: 03:37 AM :~# iptables -t mangle -A NetBalancer -p all -s 96.229.135.204 -j MARK --set-mark 101
admin@zeroshell: 03:39 AM :~# iptables -t mangle -A NetBalancer -p all -s 173.58.136.98 -j MARK --set-mark 103
then running in a loop each time when running wget with –bind-address=$ip it showed the expected IP as the result:
admin@zeroshell: 03:42 AM :~# for i in `seq 1 20`; do echo 173.58.136.98; wget --bind-address=173.58.136.98 -O - -q http://208.97.143.21/ip.php; echo; echo 96.229.135.204; wget --bind-address=96.229.135.204 -O - -q http://208.97.143.21/ip.php; echo; sleep .5s; done
