IP Forwarding

Hi,

I want to forward an IP to another IP in RHEL 4 Linux. So, i have two
IPs like 192.168.16.1 - 192.168.0.1 and i want to forward 192.168.16.1
to 192.168.0.1. So it is not just port forwarding, i want to forward
every port as well..

So if i enter to my browser 192.168.16.1 or 192.168.16.1:443 it will
be 192.168.0.1 or 192.168.0.1:443.

Is there any document for that? How can i do it?

Thanks,

Beyza Cansever

Sure....

The answer is VirtualHost!

Search the net for setting up a virtualhost with linux and Iptables.

Iptables will do it clear and perfect!

First, you have to turn on IP Forwarding
http://systemnotesorg.blogspot.com/2...ardarding.html


Then you probably want to set up some firewall rules.

I'm not sure what you are trying to accomplish, but if you want to
allow one network to access another network, you can set up forward
rules based on the interfaces (eth0 and eth1), rather than IPs.
iptables -A FORWARD -i eth1 -j ACCEPT
iptables -A FORWARD -o eth1 -j ACCEPT

Then set up masquerading to let internal machines (on eth1 network)
out to the network on eth0
iptables -t nat -A POSTROUTING -o eth0 -j MASQUERADE

This doc explains it pretty well.
