Testing With Propagation Delays

I am testing an SQL server on my LAN and the response is very quick. I have problems, though, when testing outside of work over the internet (eg. at Starbucks). There are problems that I only see when there are propagation delays.

How can I stay at work and access my local server after first looping through the internet? If I use the external I.P. address, the router just short circuits to the local machine.

I want the propagation delay. Is there some standard external proxy server I can use to do loopback? I'm wasting too much time driving to Starbucks!

I'd just use a couple SSH tunnels. Are you familiar with them?

I use the terminal shell on my mac. I have never set up any tunneling. I still need a remote machine, right? I have set up an Amazon cloud machine in the past, but that is a good bit of work.
Isn't there a service out there that just provides this? Surely other developers work with various connection qualities.

If you've got a separate box with some extra network cards, there's a package called MasterShaper for Linux that will simulate any network delays, whether it's bandwidth or latency, when used as a bridge in your network. It's got a web interface for configuration, and will generate all the graphs you want to see what's happening with your app. I've used it in the past to simulate high-latency trans-Atlantic hops for our systems.
