首先謝謝各位朋友的幫助。
我詳細講講我這裡的情況：
上網方式：ADSL－－－－ISA代理服務器－－－－交換機－－－（省略）
ISA上，有兩張網卡，對內192.168.1.1，對外192.168.88.88
用PPPOE撥號程序撥號上線後，會分得一個外部IP 219.130.*.*
現在對外網卡存在兩個IP，問題就出在這裡
下面是微軟對此問題的解釋，按此方法，我裝了SP1，但問題依舊。再次請各位高手相助！
FIX: Passive Mode FTP May Break with Multiple IP Addresses on External Interface
適用於
SYMPTOMS
Internal SecureNAT and Internet Security and Acceleration Server (ISA) Firewall clients may not open the FTP data connection to an FTP server that is using passive mode FTP (PASV). The FTP server may return one of the following error messages:
426 Connection closed; transfer aborted.
-or-
425 Can't open data connection.
In some circumstances, the FTP client may seem to stop responding (hang) or time out. FTP clients that use active mode FTP (PORT) work without error.
CAUSE
When the client establishes a passive mode FTP connection to an FTP server, the client must establish both connections. The FTP server returns the TCP port used for the FTP data connection. The FTP server expects this FTP data connection to come from the same IP address as the FTP control channel. If the connection comes from a different IP address, the FTP server may reject or close the connection because this may be a passive mode port theft attempt.
When ISA has more than one IP address bound to the external interface, the source IP address for the FTP data connection may not be the primary IP address. Instead, the source IP address may be one of the secondary IP addresses bound to the external interface. With the hotfix installed, ISA always uses the primary IP address for both types of connections.
RESOLUTION
You must install ISA Server Service Pack 1 (SP1) before you install the following hotfix.
For additional information about how to obtain the latest ISA Server service pack, click the article number below to view the article in the Microsoft Knowledge Base:
313139 How to Obtain the Latest Internet Security and Acceleration Server 2000 Service Pack
A supported fix is now available from Microsoft, but it is only intended to correct the problem described in this article. Only apply it to systems that are experiencing this specific problem. This fix may receive additional testing to further ensure product quality. Therefore, if you are not severely affected by this problem, Microsoft recommends that you wait for the next service pack that contains this fix.
To resolve this problem immediately, contact Microsoft Product Support Services to obtain the fix. For a complete list of Microsoft Product Support Services phone numbers and information about support costs, visit the following Microsoft Web site:
http://support.microsoft.com/default.aspx?scid=fh;EN-US;CNTACTMS
Note In special cases, charges that are ordinarily incurred for support calls may be canceled if a Microsoft Support Professional determines that a specific update will resolve your problem. The usual support costs will apply to additional support questions and issues that do not qualify for the specific update in question. The English version of this fix has the file attributes (or later) that are listed in the following table. The dates and times for these files are listed in coordinated universal time (UTC). When you view the file information, it is converted to local time. To find the difference between UTC and local time, use the Time Zone tab in the Date and Time tool in Control Panel. Date Time Version Size File name

02-Apr-2003 11:52 3.0.1200.260 19,216 Ftpfltr.dll
This fix also applies to the French, German, Spanish, and Japanese versions of ISA Server.
WORKAROUND
To work around the problem, use one of the following methods:
Only bind one IP address to the external interface.
Disable IP routing:
In the ISA MMC, expand Servers and Arrays.
Expand the server name node, and then expand Access Policy.
Right-click IP Packet Filters, and then click Properties.
Click the General tab, and then click to clear the Enable IP routing check box.
Click OK to close the dialog box.
STATUS
Microsoft has confirmed that this is a problem in the Microsoft products that are listed at the beginning of this article.
