If that's what the firewall requires, yes.

No. That's not what omniMapper does at all. omniMapper replies to all
requests with a new endpoint to contact, with a different host / port
in it. It is therefore useless for firewall traversal.

What you need is a GIOP proxy. There isn't one in omniORB.
Unfortunately, it isn't possible to make a GIOP proxy that proxies
arbitrary objects without seeing the IDL definitions for them. If
you've seen the IDL (or can get it dynamically from an interface
repository), it's easy enough to build a proxy.

Cheers,

Duncan.
