Hello everyone, this may be a simple fix but was wondering how to go about
the following. I have 2 systems on my network, 1 a redhat 4.x box acting as
a router and the other another system working as a dedicated proxy. The
dedicated proxy resides on the network that the router serves and I was
wondering how I could configure iptables to route port 80 requests from the
router machine to the other machine's proxy running on port 8080 - below is
some more specifics:
As shown below my router serves its dhcp off of eth 1:
[root@gateway ~]# ifconfig
eth0 Link encap:Ethernet HWaddr 00:C0:4F:5E:4E:02

My proxy runs on the ip of 10.0.0.249:8080
I know to have systems run through the proxy on the router I could use :
/sbin/iptables -t nat -A PREROUTING -i eth0 -p tcp --dport 80 -j REDIRECT
--to-port 8080
How could I modify this to reroute me to 10.0.0.249:8080 which is my other
proxy?
Any input on this would be greatly appreciated.
Thank you,
Dustin
