VPN I am trying to connect to my office using Windows VPN I can't seem to connect is there something in this router stopping me?

try to disable Vpn client in Network control panel

have you reset the airport extreme? theres a tiny hole you can push in w a paperclip. Also, do you have the latest firmware?

Buy 2 DIR 130 VPN routers and connect the two office networks via LAN-LAN VPN tunnels.
If you have the time and skills you can build two IPCOP firewall routers and connect via VPN tunnels (http://sourceforge.net/apps/trac/ipcop/wiki)

- Logon to the configuration page of your D-Link.
- Go to Advanced tab
- And Click on Firewall Settings on the left side
- Under that look for Application Gateway Level at the bottom and you must uncheck at the box on it and click on save settings at the top.

My guess is that dhcp is using the same private network scheme. Try changing your home network scheme to something different than your office.
For example:
Office = 192.168.1.x
home = 192.168.2.x

You may need to set specific ports on your router to use the voip. log onto router and go to the applications and gaming tab to set the specific ports voip needs to access Internet.

Does your office require VPN passthru to be enabled on the router? Did the firmware update reset the VPN passthru setting blocking your access?

I have the same model router at home, just checked the settings, you should be able to pass through the router with a normal vpn connection.

If you use a special VPN client, like a CheckPoint Secure VPN client, the router might block it. Also you might want to ask your office's sys admin if you are not blocked by the firewall or something similar. Your office's sys admin will prolly solve your problem since he knows your work network's configuration and setup and how to connect to it.

This example will demonstrate how to create a Virtual private Network (VPN) between two remote locations through the Internet. The VPN policy will use 3DES IPSec to securely send/receive encrypted data over the Internet. When the VPN tunnel is enabled, the two offices will virtually appear to be on the same local network. This example will consist of two DI-804V VPN Routers with a simple setup. The two remote offices in this example will be known as Office A and Office B. Both VPN Routers must already be set up and able to access each other. This is only an example, your setup will vary using the WAN IP address provided by your ISP. Please note the differences in the IP addresses for each office. We will begin by configuring the DI-804V at Office A. Start by going into VPN Settings under the Basic Setup menu. Step 1. In the Connection Name field, type in OfficeA. Click ADD. Step 2. A properties screen will appear for the new connection you have made. Fill in the appropriate information for Office A: Connection Name: OfficeA Local IPSEC Identifier: Local Remote IPSEC Identifier: Remote Remote IP Network: 192.168.1.0 Remote IP Netmask: 255.255.255.0 Remote Gateway IP: 192.170.0.2 Network Interface: WAN ETHERNET Secure Association: IKE Perfect Forward Secure: Enabled PreShared Key: 123456 Key Life: 28800 IKE Life Time: 3600 Step 3 Click SAVE. There should now be a VPN policy created for Office A. Now you will want to Save & Restart the DI-804V. Note: 123456 is an example of a preshared key, please fill in any secret preshared key you desire. Keep in mind that both sites require the same preshared key. Office A setup is now complete, we will now configure Office B with the other DI-804V, Follow the same steps previously with Ofice A to create a VPN policy. Step 1 Please change the appropriate information. Connection Name: OfficeB Local IPSEC Identifier: Local Remote IPSEC Identifier: Remote Remote IP Network: 192.168.0.0 Remote IP Netmask: 255.255.255.0 Remote Gateway IP: 192.170.0.1 Network Interface: WAN ETHERNET Secure Association: IKE Perfect Forward Secure: Enabled PreShared Key: 123456 Key Life: 28800 IKE Life Time: 3600 Step 2 Click SAVE. There should now be a VPN policy created for Office B. Now you will want to Save & Restart the DI-804V. After the VPN policies have been created for the two Offices, the two remote locations should authenticate and connect. To view the status of the VPN connection, go to the Device Status menu. On the bottom-left side of the menu, click on the VPN Status icon. A VPN Status pop-up screen will appear showing VPN connection status. If a VPN tunnel is active, the State should indicate Q-Estab. Go to a DOS prompt and ping the internal IP address of the remote network.
