A: |
None, but: http://www.elsterformular.de/navi/FAQ/faq.htm ElsterFormular 2000 will check before sending your data, if there are any new program versions available. It will establish a FTP connection for this update. Therefore you will have to open the default FTP port (port 21) in the firewall. You will need ports 8000 / 8001 / 8002 for sending of data. These ports must also be open. The protocol for sending the data is not able to use a proxy. Transmission of data via a proxy server is NOT possible.
