sql - 如何通过 ISA SERVER 2006 发布 1434 UDP 端口？

Question

我在通过 ISA 服务器进行远程应用程序连接时遇到问题：

应用程序应通过 Isa 服务器连接到应用程序服务器，但应用程序尝试通过 46.xxx 连接，UDP 1434 但 ISA 服务器无法1434 UDP像1433 TCP端口一样发布。

A network-related or instance-specific error occurred while establishing a connection to SQL Server. The server was not found or was not accessible. Verify that the instance name is correct and that SQL Server is configured to allow remote connections. (provider: SQL Network Interfaces, error: 26 - Error Locating Server/Instance Specified)
