RE: ISA2004 kills VPN outbound

Dear Gary:
Nice to see you again in the newsgroup!

>From the description, I understand that after you upgraded ISA 2000 to ISA
2004, the VPN connection no longer worked and you received the error 619
and 628. If I am off base, please do let me know.

Before we go any further, please first re-run the CEICW Wizard, this will
help us automatically configure the network settings, and then follow this
KB article to create the appropriate access rule for outbound PPTP
connection.
How to permit PPTP clients to access the external network through ISA
Server 2004
http://support.microsoft.com/?id=838245

(You can follow this article when running the CEICW Wizard:
825763 How to configure Internet access in Windows Small Business Server
2003
http://support.microsoft.com/?id=825763 )

Then, establish the VPN connection again, does it work this time?

If the problem persists, we may need to make a further analysis. Please
help me gather the following information in order to narrow down this issue:

1. Do you have firewall client installed? If so, please try disabling the
FW client and configure the client as a SecureNAT client. When we make a
PPTP-based connection from an internal client to the internet VPN server,
we cannot have the firewall client installed because the ISA Server
Firewall Client program does not support a PPTP-based VPN connection. You
can refer to this article for more information:

When you use the ISA 2004 Firewall Client program, you cannot make a
PPTP-based VPN connection
http://support.microsoft.com/?id=887006

Note: SecureNAT client is the machine that its default gateway is the
internal IP of the ISA server.

2. Are you using a Linksys BEFSR41 router? The error 628 may occur if your
VPN server is located behind a Linksys BEFSR41 router.
Remote VPN Clients Cannot Log On to Network
http://support.microsoft.com/default.aspx?scid=KB;EN-US;329858

3. If the client directly connects to the Internet, can the PPTP connection
to the same VPN server work? This can verify if the remote VPN server is
configured well.
If this works, would you please tell me if this problem occurs on all the
internal clients?

4. Please help to gather the ISA Info:

1) Download the file from the following URL:

http://www.isatools.org/isainfo/ISAInfo.zip

2) Extract all files to a folder on ISA server.
3) Double click Isainfo.js. This will generate 2 files
ISAInfo2004-<computer-name>.log and ISAInfo2004-<computer-name>.xml in the
current folder.
4) Please send these files to me.

5. Please also help to gather the ISA logs:

1) Schedule a down time.

2) Open ISA 2004 management console.

3) Expand the server node and highlight 'Monitoring'.

4) In the right pane, switch to the 'Logging' tab, make sure the 'Task
Pane' is showed there.

5) In the 'Task Pane', click 'Configure Firewall Logging' under 'Logging
Tasks', and then switch the 'log storage format' from 'MSDE database'
(default) to 'File'.

6) Switch to the 'Fields' tab, click 'Select All', and then click OK.

7) In the 'Task Pane', click 'Configure Web Proxy Logging' under 'Logging
Tasks', and then switch the 'log storage format' from 'MSDE database'
(default) to 'File'.

8) Switch to the 'Fields' tab, click 'Select All', and then click OK.

9) Click 'Apply' to save changes and update the configuration.

10) Temporarily disable the Firewall service. To do that, please click
Monitoring | Services tab, and then right click 'Microsoft Firewall' to
choose 'Stop'.

11) Clear the current existing W3C logs. To do that, go to the log saving
directory and clean any existing .W3C logs. By default, the logs will be
saved to 'C:\Program Files\Microsoft ISA Server\ISALogs'. (Some MDF may not
be able to deleted, that's normal.) You may backup them first and then
delete them.

12) Go back to the ISA 2004 management console, and then Start the stopped
'Microsoft Firewall' service.

13) Reproduce the problem, stop the service, and then gather the resulting
W3C files to me for analysis.

Note: Please also let me know the IP address of the testing client/server
and the remote VPN server so that I can filter the data.

I appreciate you taking time to perform the above steps and gather the
information. Please feel free to let me know if you have any questions or
concerns.

I look forward to hearing from you.
Have a nice day, Gary! :)

Best Regards
Edward Tian(MSFT)

| Hi,
|
| Since upgrading from ISA2000 to ISA2004, neither the server nor clients
| behind ISA can VPN out. Server gets error 619, clients get error 628.
This
| worked under ISA2000. Is there an access rule I need to set up?
