port forwarding form IP range

[Nilesh]

Dear all,

I have two squid proxy servers and two ISP 

1)	192.168.0.1 port 3128
2)	192.168.0.3 port 3128

We have around 70 comps assigned IP’s between
192.168.0.4 to 192.168.0.250
The default proxy we are using is 192.168.0.1 which is
on the ISP 1.
Now I have configured 192.168.0.3 squid proxy server
on ISP 2 line.
Both ISP 1 and ISP 2 are landing (connected) on the
same Switch.

Now I want setup the request coming from IP range
(192.168.0.10 to 192.168.0.20) for the 
192.168.0.1:3128 
Will be forward to 192.168.0.3:3128
So the users from this IP range will access only
192.168.0.3 proxy server.

Could any one please help me which rules should I use
in IPTABLES .

I have attached herewith my rc.firewall file.

Please help me.

Regards
Nilesh.
