Loadbalance caching dns server

[Stefan Certic]

Hi,

That can be achieved using iptables:

iptables -A PREROUTING -i eth0 -p tcp --dport 53 -m state --state NEW -m
nth --counter 0 --every N --packet 0 -j DNAT --to-destination
192.168.1.98:53
iptables -A PREROUTING -i eth0 -p tcp --dport 53 -m state --state NEW -m
nth --counter 0 --every N --packet 1 -j DNAT --to-destination
192.168.1.99:53

Where N represent packet number.

Regards,
