I'm developing a web app and I need to be able to get incoming traffic from 3rd party services I use. This is a classic webhooks situation: I send a request with a return address and receive the response (via HTTP) some time later to the given address.

The simple solution would be to provide my external IP address and forward the incoming traffic from the router to my machine. However, I'm working in a large office and I cannot control the router configuration. I'm looking for a different way to achieve that.

I do have servers online. I can have a daemon running on one of those servers, which will handle the incoming traffic. I can run a parallel daemon on my machine, which will keep an open connection with the remote daemon (over ssh preferred) and when an inbound traffic is received by the remote, it will send it to the local, which will send it to the correct port on my machine, as if it was received in the natural way.

Is there any ready-made solution for that?

PS. I'm on OS X and my server is Ubuntu.
