> You (the vendor) can ask the customer to open their firewall for your software to communicate with the outside world (e.g. your own datacenter or third party services), but customers will usually be reluctant to open their firewall more than necessary.
Vendors that try tricks like this to work around the firewall team, as backlogged and inefficient as they are, will lose deals and credibility, 100% guaranteed. And I love ssh -R and stunnel, for what it's worth.
The easier way to get what you want is to get someone technical with political capital (they exist) to buy into what you're selling so that they can tell the firewall team to make exceptions during a trial period.
