DIF Freedom communicates with the trading server via various TCP Ports. Client Station attempts to automatically detect the correct communications settings from your Internet Explorer setup.
If you are having problems using DIF Freedom and you are situated behind a firewall or proxy server, check with your system administrator that the relevant ports are open as follows:
If it is not possible to open this port due to strict firewall policy, Client Station can be configured to use:
The proprietary TCP/IP protocol (non-HTTP) is the preferred operating mode as it allows faster data transfers between the server and the Client Station.
If Client Station is configured to communicate using HTTP tunnelling (the Use HTTP check box is checked), the proxy is assumed to be a HTTP proxy and the SOCKs protocol is not used.
If your proxy uses the SOCKs protocol version 4a, User Name only is supported by this protocol. SOCKs protocol version 5 supports both User Name and Password.
HTTP proxies can be configured for User Name and Password for basic or digest authentication.
