[omniORB] -ORBendPoint, VPN tunnel IP and omniORB 4 vs. omniORB 2.8.0.

Use the -ORBendPointNoListen option when specifying the VPN endpoint.  Also
add a regular -ORBendPoint and/or an -ORBendPointNoPublish to specify the
actual endpoint to listen on.

I currently have a CORBA server (omniORB 2.8.0) that can run behind a VPN
connection.  Clients in the corporate LAN connect to this server.

This server determines it's VPN tunnel IP (using something like
www.ipchicken.com) and uses that in it's IOR by setting
OMNIORB_USEHOSTNAME.

Now I'm trying to port this server to omniORB 4.0.3.  Instead of setting
the OMNIORB_USEHOSTNAME variable, I'm doing this:

             -ORBendPoint giop:tcp:<vpn tunnel IP>:<some port number>:

Unfortunately does not work for the VPN tunnel IP.  Trying to do so results
in an exception, and the following error message in my console app:

             omniORB: Error: Unable to create an endpoint of this
description: giop:tcp:<vpn tunnel IP>:<some port number>:

It appears that there is an extra check being done in 4.0.3 that was not
being done in 2.8.0 that prevents this from working.  If the specified
IP/host is not a valid IP/host for one of the local network interfaces,
then the request is rejected.

Is there a way to turn this check off?  Or should I be doing this some
other way?

Thanks,
-Mike
