Re: How to securely connect to IIS outside the firewall.

Dave,

If IIS is your platform of choice for hosting Web applications, and the IIS
server is outside your network, and you want secure communication with
OS/400, then I'd recommend using SSL between your IIS application and the
OS/400 HTTP server.

The Windows wininet.dll supports SSL.  There may be an Active X wrapper
available somewhere.  Just open a secure connection and use the HTTP
functions within the wininet.dll to communicate with the OS/400 HTTP server.

I offer an OS/400 HTTP Server "plug-in" that provides a message service,
similar to MQ Series, but inexpensive.  It would handle the interface
between the OS/400 HTTP Server and your ILE programs.  Your ILE programs run
as server daemons.  They are started and ended via command.  They could
process transactions and return data to your IIS application.  Contact me
privately if you'd like to discuss the details.

This approach is a lot less complex then VPN, but equally secure.  Actually
it's probably more secure than VPN, because the service is limited to HTTP.
It's also a lot less expensive than MQ Series.

Thank you for your consideration,
