Ok, I'm not clearly explained.
I'm using SNAT to change the source ip address because iproute2 set an
ip address that I don't like.
So, I have inserted the following line in my firewall script:

iptables -t nat -I POSTROUTING -s iproute2_chosen_ip --protocol tcp
-j SNAT --to i_want_this_first_ip --to i_want_this_second_ip

But everytime I connect to the internet always "i_want_this_first_ip" is
chosen to
do the SNAT.
