IP ROTATION VIA IP TABLES

First we need creating Interface aliases for your public IPs.


Let's say you have 5 ips

#ifup eth0:1
#ifup eth0:2
#ifup eth0:3
#ifup eth0:4

Now the iptables part.make sure your iptables support for statistic match module.

# iptables -m statistic -h
......
......
......
statistic match options:
--mode mode Match mode (random, nth)
random mode:
--probability p Probability
nth mode:
--every n Match every nth packet
--packet p Initial counter value (0 <= p <= n-1, default 0)
Next continue with iptables rule for rotating source IP addresses.

# iptables -t nat -I POSTROUTING -m state --state NEW -p tcp --dport 25 -o eth0 -m statistic --mode nth --every 5 -j SNAT --to-source 202.XXX.XX.2
# iptables -t nat -I POSTROUTING -m state --state NEW -p tcp --dport 25 -o eth0 -m statistic --mode nth --every 5 -j SNAT --to-source 202.XXX.XX.3
# iptables -t nat -I POSTROUTING -m state --state NEW -p tcp --dport 25 -o eth0 -m statistic --mode nth --every 5 -j SNAT --to-source 202.XXX.XX.4
# iptables -t nat -I POSTROUTING -m state --state NEW -p tcp --dport 25 -o eth0 -m statistic --mode nth --every 5 -j SNAT --to-source 202.XXX.XX.5
# iptables -t nat -I POSTROUTING -m state --state NEW -p tcp --dport 25 -o eth0 -m statistic --mode nth --every 5 -j SNAT --to-source 202.XXX.XX.6

done
