Kanchi and Ken mentioned basically the same. Bottom line, if they believe they can tell you what holes to pry into your firewall, they need to be hit with the clue stick. It's your prerogative to choose whatever port number you support for incoming HTTP. If you have set up your S/W to listen on http://your.company.com:8081/dumpyourAS2here, then that's what you tell them to send it to. If they choose to listen on http:/big.corp.ca:ZZ/AS2listener, where ZZ is one of those five port numbers, that's fine, too. If they tell you they'll be connecting from any of those five port numbers to your listener, you just say 'fine, I'm not bothered with your client port number, anything 1-65something will do, I'll just open up that IP number you're sending from". But, if they say "you must listen on ports like ZZ", you just need to tell them "sorry, they're already in use, please find a n AS2 software supplier that will allow you to use whatever port I tell you to send to". Of course, business relationship may prevent you from doing that, and you may have to resort to port mapping (Apache will do that, Tomcat as well, and many more, including routers/firewalls). But OTOH, why should you and all your fellow partners to this big corp pay for their stupidity? (I know, because they're big).
