title: Heroku Static IP for SFTP
body: <p>I have an application deployed to Heroku. I'm using a service that requires me to access their SFTP server using a static ip address. I know Heroku dynos are unreliable in this regard. I have successfully achieved this using the Proximo addon, however, its too expensive for the amount of traffic that I'll be sending (around 500 MB/month). Is there an alternate to this? I'm inclined towards using an EC2 instance but not quite sure what's required to create a proxy or whatever.</p>
