Can I use stunnel to communicate across a firewall?
As long as the tcp traffic is allowed to traverse your firewall, absolutely. You’re most likely to convince your firewall administrator to allow secure traffic from inside to outside. In fact, if your firewall is doing NAT, you can probably stunnel out from your machine to an internet machine without any firewall re-configuration. Specifically, have your firewall administrator allow outbound connections from your machine to the remote (internet) machine on the specific port you wish to connect to. Be sure to discuss these issues with your administrator. They don’t enjoy people penetrating their firewalls without their consent.
