firewall + loadbalancer on the same machine

[Atif Ghaffar <aghaffar@xxxxxxxxxxxx>]

Hi all,

I would like to know: Is it possible to run iptables firewall and ipvs 
loadbalancer on the same machine.  Or Can I access or forward requests 
to loadbalanced service address if it is on the same machine?
Until recently I have a set of machines which do the firewall and 
another set of machines that do the ipvs.
The ipvs is needed only for one or two services. so I want to put that 
also on the same machines as the firewalls.

The firewall+loadbalancer will be doing something like this.

Firewall rule:
NAT 212.232.121.121 port 80 to 192.168.30.121 port 80
Both IP addresses are of firewall interfaces

Loadbalancer rule:
Send all traffic on ip 192.168.30.121 port 80 to ¨
the following NATed addresses

192.168.100.101 port 80
192.168.100.102 port 80
192.168.100.103 port 80


thanks in advance.

best regards.
Atif
