Two questions to start, checking the Apache logs on both servers.

1. What is shown in the reverse proxy server's Apache access log? Can you
tell if proxy Apache is receiving and forwarding the request properly to
the IBM i?

2. Is the IBM i receiving the request correctly? The IBM i's Apache server
logs may contain useful information, too.

I have a web service, created and installed into the iSeries Integrated Web
Services Server.

I have a PC that is outside the DMZ and which has Apache on it. The Apache
server there was set up as a Reverse Proxy server that interfaces with the
Apache server running on the iSeries which is behind the DMZ.

Now.if I get on the local VPN, and test calling that web service by going
through the Reverse Proxy, I am able to connect to the Web Service fine and
pull my data back.

However, if I get out of the VPN (or get on another non-VPN connected PC)
and try to contact that Web Service via the Reverse Proxy server, what I get
back instead is an error telling me that the Soap request cannot be decoded,
which makes sense as the value it returns to me is NULL.

I am wondering if this is an authority issue on the iSeries/Apache server.or
possibly an authority issue between the Reverse Proxy Server and the Apache
server on the iSeries.

Honestly I'm at a loss as to what to do next on this to try to narrow down
the problem.

I am open to any and all suggestions or thoughts on this.
