DIF Freedom - Comunicações - Firewall/Proxy
DIF Freedom comunica com o seu servidor através de várias portas TCP. A plataforma tenta detectar automaticamente as definições correctas do seu Internet Explorer.
Se está a verificar a ocorrência de problemas quando utiliza a sua plataforma DIF Freedom e está protegido por firewall ou proxy server, verifique com o seu administrador de sistema que as portas relevantes estão abertas e acessíveis como descrito a seguir:
Para a melhor performance execute os seguintes passos:
- Port 1001 should be open in your firewall/proxy server for outgoing access to canalsimul.difbroker.com (IP Address 193.178.175.38). This port is used for encrypted communications with the trading server.
- A HTTP port (port 80 or 8080) must be open; this port is used for program downloads and for web pages in Client Station.
Optimal Solution
| Raw Protocol Direct | |
| Remote Server Settings | |
| Trader Server Name | canalsimul.difbroker.com |
| Use HTTP | No |
| Port | 1001(must be open in Firewall) |
| Proxy Server Settings | |
| Connect Via Proxy Server | No |
| SOCKS Protocol Version | N/A |
| Server Name | N/A |
| Port | N/A |
| Username | N/A |
| Password | N/A |
| Notes: Use this configuration if you have a Proxy/Firewall Client. No further proxy information should be required by Client Station. If your site uses a firewall, Port 1001 must be opened for IP address 193.178.175.38 or DNS name canalsimul.difbroker.com. | |
| Advantages: This is the preferred operating mode as it allows faster data transfers between the server and the Client Station. | |
Soluções Alternativas
Se não for possível abrir esta porta devido ao acesso restrito da firewall, a plataforma do cliente pode ser configurada para utilizar:
- HTTP Tunneling via HTTP Proxy. This has the advantage of not needing port 1001 to be opened but performance is lower than the raw protocol solution.
- SOCKS Proxy
- HTTP Tunneling Direct
| HTTP Tunneling via HTTP Proxy | |
| Remote Server Settings | |
| Trader Server Name | canalsimul.difbroker.com |
| Use HTTP | Yes |
| Port | N/A |
| Proxy Server Settings | |
| Connect Via Proxy Server | Yes |
| SOCKS Protocol Version | N/A |
| Server Name | DNS or IP Address of HTTP Proxy Server |
| Port | Typically 80 or 8080 |
| Username | Userid for proxy authentication |
| Password | Password for proxy authentication |
| Notes: If port 100l cannot be opened (for example due to strict firewall policies), the Client Station can be set up to run in HTTP mode where all communications between the server and the Client Station use the HTTP Port. | |
| Advantages: Port 1001 does not need to be open on the firewall. | |
| Disadvantages: This mode of operation is considerably slower than the raw protocol solution. | |
| SOCKS Proxy | |
| Remote Server Settings | |
| Trader Server Name | canalsimul.difbroker.com |
| Use HTTP | No |
| Port | 1001(must be open in Firewall) |
| Proxy Server Settings | |
| Connect Via Proxy Server | Yes |
| SOCKS Protocol Version | 4(a) or 5 |
| Server Name | DNS or IP Address of Socks Proxy Server |
| Port | Typically 1080 |
| Username | Userid for proxy authentication |
| Password | Password for proxy authentication (version 5 only) |
| Notes: If your site uses a firewall, Port 1001 must be open for IP address 193.178.175.38 or DNS name canalsimul.difbroker.com | |
| Advantages: This is the preferred operating mode as it allows faster data transfers between the server and the Client Station. | |
| Disadvantages: Requires a Proxy Server that supports the Socks Protocol. | |
Remote Server Settings
| Trade Server Name | This is the DNS name or IP address of the trading server and should not be changed unless instructed to do so by us. |
| TCP/IP Port | The Client Station supports a proprietary TCP/IP protocol for communications with the trading server. This protocol offers efficient communications with the trading server and we recommend it's use where possible. |
| Use HTTP | To set up the Client Station to communicate with the trading server using HTTP tunneling instead of the proprietary protocol, check the Use HTTP check box. This may be required to allow the Client Station to communicate with the trading server through your firewall or proxy server. 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. |
| Proxy Server Settings | |
| Connect via proxy server | Check the Connect via proxy server check box to set up set up the Client Station for communications through a proxy server. |
| SOCKs | If Client Station is configured to communicate using the proprietary protocol (recommended configuration), the SOCKs protocol must be used on your Proxy Server and the correct SOCKs version must be selected. Select the SOCKS protocol version in use on your Proxy Server (versions 4a and 5 are supported). 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. |
| DNS or IP Address | Enter either the DNS name or the IP address of your proxy server as seen from your network. We recommend the use of DNS names where possible as this can make traversing address translation (NAT) solutions simpler. |
| User Name and password | Enter the User name and Password if required by your proxy server. 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. |
| Port | Typical Proxy Ports: HTTP Proxy : 80 or 8080 SOCKS Proxy : 1080 |
| Communications Settings | |
| Enable communications log | Check the Enable communications log check box to enable logging of communications between the Client Station and the trading server. This is typically done for troubleshooting purposes. |
