Hi Dragonis,
Yes, it is possible to access to logon external if you have an Edge server in DMZ.
The link you provided using three public IPs, so it is not apply for you.
You can use one public IP with NAT to the private IPs of Lync Edge three services (Access Edge service, Web conferencing service and A/V service).
You can refer to the following link about deploy Edge server with One Public IP:

The Reverse Proxy server is an optional, external component that is not a Lync Server role and is not defined in the Lync Topology.
The reason this component is considered optional is because without it deployed an external Lync client can still connect to Lync and most features will function (IM, Presence, Calls, Desktop Sharing, etc.) as will federated communications.
Only the feature listed on the link below will not be available to external clients, which although are important in a fully functional deployment they are not critical.
Yet best practice is always to provide for these features by publishing the internal web services. A Reverse Proxy is also required to support any external Mobility client connectivity.
