Scp and sshexec tasks will work through a firewall, just as ssh and scp
executables will. There is a difference, however, between going through
a firewall and an http proxy server. Ssh cannot be proxied through an
http proxy server.

In the case of a firewall, you will need to make sure that port 22 is
forwarded to the appropriate machine inside the firewall, essentially
poking a hole in the firewall to allow the access required.
