RE: Default Gateway on VPN subnets



Hi:
Thank you for posting here. I am sorry for the delayed response due to
weekend. Please understand that the newsgroups are staffed weekdays by
Microsoft Support professionals to answer your systems and applications
questions. Your understanding is greatly appreciated!

>From the description, I understand that once you established the VPN
connection to the SBS Server from a remote 2003 Standard server, the
default gateway of the remote server will be automatically changed to the
default gateway of the SBS Server. If I have misunderstood your concern,
please do let me know.

Based on my research, the root cause of this issue is because the VPN
connection will use its gateway to replace the current gateway.

Once you install the Connection Manager package (sbspackage.exe) created by
the SBS Remote Access Wizard, you do not have the option to modify the
predefined settings within Network Connections at the client.

This is because the settings are located Documents and
Settings\<username>\Application
Data\Microsoft\Network\Connections\Cm\remote\remote.cms (Predefined)

If you do not want Connect to Small Business Server's connectoid to use
default gateway on remote network, open the remote.cms file and change
Gateway_On_Remote from 1 to 0.

For example (This apply to the VPN connection):
[TCP/IP&Connect to Small Business Server Tunnel]
Gateway_On_Remote=1
-to-
[TCP/IP&Connect to Small Business Server Tunnel]
Gateway_On_Remote=0

For example (This apply to the dial-up connection):
[TCP/IP&Connect to Small Business Server]
Gateway_On_Remote=1
-to-
[TCP/IP&Connect to Small Business Server]
Gateway_On_Remote=0

[Note] If you manually created the VPN connection by using "Create a new
connection" wizard on the client computer, please follow these steps to
solve the issue.

1. Open Network Connections.
2. Right-click the VPN connection and click Properties.
3. Click the Networking tab and double-click Internet Protocol (TCP/IP).
4. Click Advanced and uncheck the "Use default gateway on remote network".
5. OKs to confirm the changes.

I hope the above info helps. Please feel free to let me know if there is
anything I can do for you.

Have a nice day!

| I am setting up a VPN network between several offices. The main office

log-on?
| or FRS sync'???).
| SBS def' gtw' 192.168.16.1, the remote server's def' gtw' should be
| 192.168.48.1 but gets changed to 192.168.16.1.
| I could edit the client config file to 192.168.418.1 however when the
second
| and third remote offices are connected they will then suffer the same
problem.
| If I delete the Default Gateway line completely from the client config
file
| will this cause any unexpected problems/errors?
