Yes, SmartWhois supports SOCKS firewalls and HTTP/HTTPS proxy servers (they must support the CONNECT method). If your firewall is not SOCKS-compliant, you'll have to configure it to allow network traffic on TCP ports 43 and 80. Please refer to your proxy server's documentation or contact your network administrator for information on configuring (mapping) proxy ports. Also, see the
Using SmartWhois From Behind a Firewall chapter of the help file for more detailed information.
