Access virtualmin from off network

Sorry to post another issue so soon, but I have a few issues that I am running into. I am posting them one by one in hopes that fixing one will fix others (getting the email working did actually fix another issue I was having)

For some reason when I am not on the same network as my server, I can not login to Virtualmin. When I try to access Virtualmin (https://server1.mydomain.com:10000), my browser just spins it's wheels and then times out. However, I am able to access Usermin (https://server1.mydomain.com:20000) just fine. When I am on the same network as my server, I can login to either.

Is there a setting in Virtualmin which would cause this?
