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 27290 and 27292.  If you use a standalone Windows Support Server, that by default listens on port 27291, so that would need to be configured to allow the UnForm server to connect to that port on the Support Server machine.

In addition, some firewalls block programs as well as ports.  The programs are uf90drun and httpd.  On Windows, both programs will be in the UnForm installation path, and be named "PxPlus" for the uf90drun.exe program, and "Apache HTTP Server" for the httpd.exe program.  On Unix, the local http server is used, rather than one inside the UnForm path, but the uf90drun program is found in the UnForm path.
