Hi,
I need a gateway for our new office. I'd like it to run Fedora. What
are my options? I'd like to be able to do the following:

  - provide VPN back to the main office
  - provide basic masquerading of hosts on inside network
  - be small enough to fit on a shelf. Preferably fanless
  - web-based administration
  - ssh access


Have a look at https://www.pcengines.ch/apu2.htm  These offer 2 or 3 ethernet 
ports, small form factor, and fanless.  Fedora is not a good choice for this
role unless you are willing to devote time and effort to testing new versions 
as they appear.  In that case you would want a couple systems so each new
release could be tested before going into serivice.   Pcengines has centos7 
images for apu systems.
 
We're experienced admins, so a simple interface isn't specifically
necessary, but desired.

It's only for a few remote office workers, so it doesn't have to be
particularly powerful, but should be responsive enough to support
regular ssh and VPN activity.

Avoid USB NIC's.     Have a look at pfSense
