- On the wizard, click Next to continue.
- Click Next to accept the default name.
- Uncheck the Activate the default response rule and click Next.
- Make sure the Edit Properties option is checked and click Finish.
Then starting with the properties window that popped up, follow these steps:
- Click Add.
- On the wizard, click Next.
- Make sure that the This Rule Does Not Specify A Tunnel option is marked and click Next.
- Select the Local Area Network option and click Next.
- Select Use This String To Protect The Key Exchange, type the same pre-shared key you created on RouterOS, and click Next.
- Click Add to create a new IP Filter List.
- Click Add and follow the wizard, selecting My IP Address as the Source and the IP address of the RouterOS as the Destination.
- On the window for the new IP Filter List, click OK.
- Select the new IP Filter List you just created from the list and click Next.

- Uncheck the Properties option and click Finish.
Now you need to bring up the Services snap-in on the Console so you can restart the IPSec service. Then go back to the IP Security Policy snap-in, right-click the new policy and select Assign. Finally, you should be able to connect to the VPN.
