In the post describing that server: > They required a dhcp, an internal DNS, an Apache + PHP server for some internal (and a couple of external) websites, a file server accessible via both NFS and Samba (as Windows PCs needed access), an internal SMTP connecting to an external relay to ensure faster email dispatches for employees given their unstable connectivity, and a few other nuances. It's running basically everything. But even if it was exposed only internally, that's usually only one other issue or misconfiguration away from being fully exposed again.
