[users@httpd] How to set up a NAT Bounce Back in Apache?
Hi,
I am trying to find an example of how to setup a NAT Bounce Back in Apache.
Can anyone point in the direction of an example or some documentation?
Thanks in advance!

Hi Eric,
yes i would say so because i dont know a IP balancer for apache. and i
think your description points to a potential asymetrical routing issue
which only happens with a IP balancer.

Hi Aaron,
Thanks for your feedback so then you are saying I don't need to worry about it?
Thanks!

i think the problem mentioned here is a "asymmetrical routing issue"
you have with IP load balancer, where a Apache behaves differently
it acts like a proxy with the additional feature of balancing the
load and not doing a IP balancing like a BigIP
so this shouldn't be an issue with an Apache

Consult your LBR's configuration guide on how to set this

In the past I have done this with F5 BigIP. So I guess I
just need to create a VIP and a pool or range of addresses
in the virtual host config?
Thanks for your input!

In Apache, you can just list any number of addresses
in each
<VirtualHost> and any number of ServerAlias'es
for name-based vhosts,
so no magic is required to access them from the
internal network.
Can you describe the problem more directly?

Hi Eric,
I am trying to setup load balancing for Oracle Portal using Generic Apache and the documentation tells me
"Configure the LBR to perform Network Address Translation (NAT)
bounce back for loopback requests coming from the PPE running on m1.abc.com.
This ensures that when the PPE makes a loopback request to OracleAS Web
Cache, there are no errors.
NAT bounce back is set up differently on individual LBRs. Consult your
LBR's configuration guide on how to set this up.
"
In the past I have done this with F5 BigIP. So I guess I just need to create a VIP and a pool or range of addresses in the virtual host config?
Thanks for your input!

In Apache, you can just list any number of addresses in each
<VirtualHost> and any number of ServerAlias'es for name-based vhosts,
so no magic is required to access them from the internal network.
