reverse proxy server error

We try to test our proxy server through IBM_HTTP_Server/2.0.47.1 - PK07831 Apache/2.047, but not success. Here is the error msg:
[debug] proxy_util.c(11181): proxy HTTP: fam 2 socket created to connect to xx.xx.xx.com
[error] (78)Connection timed out: proxy: HTTP: attempt to connect to 172.xx.xx.xxx.xx (xx.xx.xx.com) failed

Can anyone tell us what is wrong and what should we do? Thank you for your help

Thank you for your response.

Here is what we try to do: we have two web application servers: Websphere, application languge is java, running on UNIX, other web application server is IIS, application is coding by asp, running on NT. When user request NT application from UNIX(home site), we need to redirect response to the user and connect user to NT via an IHS apache (outside of DMZ) proxying for NT address, we don't want NT address expose to the internet. User are internet user outside of internet fire wall, UNIX and NT are inside DMZ.

You said internal addresses, does that mean not registered address? and "proxy is misplaced", where should we place it based on what I described above?

I understand what you said that proxy may misconfigured, but where and how to correct it, can you give me clue?

Thanks

Hi, SaP
Need your help. Do you need more info? Thanks

internal addresses are used for local network, not internet.
so, if you are developing an internet oriented proxy, it obviously wont
work.

I am new to the network, can you please give me more detail? What you said is we need translate internal address to internet address? If this is correct, how? Should we use Network Address Translation(NAT) or proxy server can handle the translation? thanks for your help
