FIREWALL CONFIGURATION

It is common for a firewall to block access to any of the ports that the UnForm server or Apache HTTP server listen on.  For ports, all that is needed is to open the two listening ports, which default to 27500 and 27502.

In addition, some firewalls block programs as well as ports.  The programs are uf110drun and uf110d.http.  On Windows, these files have .exe extensions.
