Hi,

Yes Linux can be a load balancer:

if you want to balance the load to the 3 addresses 10.0.0.5, 10.0.0.6 and 10.0.0.7, then you can do as follows :

# iptables -t nat -A POSTROUTING -o eth0 -m nth --counter 7 --every 3 --packet 0 -j SNAT --to-source 10.0.0.5
# iptables -t nat -A POSTROUTING -o eth0 -m nth --counter 7 --every 3 --packet 1 -j SNAT --to-source 10.0.0.6
# iptables -t nat -A POSTROUTING -o eth0 -m nth --counter 7 --every 3 --packet 2 -j SNAT --to-source 10.0.0.7

Of course you need to compile the nth extention module into the iptables.

You could also look at a number of the software solutions for this type of thing which would include 'fail-over' etc:
