Chapter 23 Troubleshooting
Note: In this example, it is assumed that client hosts use the WinRoute DNS Forwarder or local DNS server (traffic must be allowed for the DNS server). If client stations used a DNS server in the Internet (this configuration is not recommended!), it would be necessary to include the DNS service in the rule which allows unlimited Internet access.
23.6 FTP on WinRoute’s proxy server
Proxy server in WinRoute, version 6.0.2 and later (see chapter 5.5), supports FTP. When using this method of accessing FTP servers, it is necessary to keep in mind specific issues regarding usage of the proxy technology and parameters of WinRoute’s proxy server.
1.It is necessary that the FTP client allows configuration of the proxy server. This condition is met for example by web browsers (Internet Explorer,
Firefox/Netscape/Mozilla/SeaMonkey, Opera, etc.), Total Commander (origi- nally Windows Commander), CuteFTP, etc.
Terminal FTP clients (such as the ftp command in Windows or Linux) do not allow configuration of the proxy server. For this reason, they cannot be used for our purposes.
2.To connect to FTP servers, the proxy server uses the passive FTP mode. If FTP server is protected by a firewall which does not support FTP (this is not a problem of WinRoute), it is not possible to use proxy to connect to the server.
3.Setting of FTP mode in the client is irrelevant for usage of the proxy server. Only one network connection used by the FTP protocol is always established between a client and the proxy server.
Note: It is recommended to use FTP over proxy server only in cases where it is not possible to connect directly to the Internet (see chapter 5.5).
Example of a client configuration: web browser
Web browsers allow to set the proxy server either globally or for individual protocols. In our example, configuration of Microsoft Internet Explorer 6.0 focused (configuration of any other browsers is almost identical).
1.In the browser’s main menu, select Tools → Internet Options, open the Connections tab and click on the LAN Settings option.
2.Enable the Use a proxy server for your LAN option and enter the IP address and port of the proxy server. IP address of the proxy server is the address of the WinRoute’s host interface which is connected to the local network; the default port of the proxy
