Problem When i ping (-t) on the U30 from the main office

My company have NETASQ U30 & U70 on it branches connected through VPN connection to the main office to the SonicWall Firewall. i am using IPSec VPN, the setting on all of the three units are the same, U70 is functioning very well, while there’s a problem in U30 VPN connection; The issue is: When you ping (-t) on the U70 from the main office (which has SonicWall firewall) – it replies instantly without any problem, shared data opens also instantly. When you ping (-t) on the U30 from the main office (which has SonicWall firewall) – it gives request time out for couple of minutes, shared data cannot be open !! After a couple of minutes of ping (-t) it gives reply answer, as it seems the sessions opens, and then you can access shared data, if you close down the ping then wait for few minutes and ping again the issue appears again!!? It seems (in my opinion) the 3 way handshaking is taking too much time on U30, while in U70 it works perfectly. I need to help

SOURCE: Can't connect to AT&T VPN

I'll need to know what router you're using, make and model, for more specific help, but sometimes there is an option for IPSec passthrough. For example, on my Linksys Wireless Router WRT54G, there is a set of buttons under Security/VPN that are entitled IPSec Passthrough, PPTP Passthrough, and L2TP Passthrough. Since I don't know what router you're using, I can't tell you wether or not your router supports such functions or not, but if it does, you need to enable them.

SOURCE: Cannot connect to SonicWall VPN

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

SOURCE: Unable to reach firewall periodically

If you are using the firewall as the DHCP server, you may need to check the DHCP lease period on the firewall & increase it if required.

Cannot link vpn. direct from internet provider works. when try connection via d-link dir625 does not connect. does allow internet access


Ok to Setup you VPN follow the instructions below. You can configure DI-804HV, DI-808HV, and DI-824VUP+ by web management interface. Type 192.168.0.1 (The LAN IP is 192.168.0.1 by default) in the browser, and then input user name: admin (there is no password by default) to pass authentication of web management interface. Then finish the configurations as showed below on Gateway A and Gateway B. Configurations of Gateway A 􀂾 Model: DI-804HV (DI-808HV, or DI-824VUP+) 􀂾 Firmware version: v1.40 (You can download the latest firmware on D-Link’s website.) 􀂾 WAN IP Address: 14.15.16.17 (Static IP) 􀂾 LAN IP Address: 10.5.6.1 (Subnet Mask: 255.255.255.0) 􀂾 VPN Configurations: 􀂄 Enable VPN function on Gateway A. 􀂄 Tunnel Name: toGatewayB 􀂄 VPN Method: IKE (Main mode) 􀂄 Local Subnet: 10.5.6.0 􀂄 Local Netmask: 255.255.255.0 􀂄 Remote Subnet: 172.23.9.0 􀂄 Remote Netmask: 255.255.255.0 􀂄 Remote Gateway: 22.23.24.25 􀂄 Pre-share Key: hr5xb8416aa9r6 􀂄 IKE Proposal (Please remember to add the correct proposal ID into the list of IKE Proposal Index when you finish inputting the following information.) 􀀹 Proposal Name: toGatewayB 􀀹 DH Group: Group 2 􀀹 Encryption Algorithm: 3DES 􀀹 Authentication Algorithm: SHA1 􀀹 Life Time: 28800 􀀹 Life Time Unit: Second 􀂄 IPSec Proposal (Please remember to add the correct proposal ID into the list of IKE Proposal Index when you finish inputting the following information.) 􀀹 Proposal Name: toGatewayB 􀀹 DH Group: Group 2 􀀹 Encapsulation Protocol: ESP 􀀹 Encryption Algorithm: 3DES 􀀹 Authentication Algorithm: SHA1 􀀹 Life Time: 3600 􀀹 Life Time Unit: Second 4. Verify the VPN connection Before you start to establish VPN connection between Gateway A and Gateway B, please make sure the Internet connection between Gateway A and Gateway B is workable. You can use “Ping Test” tool on Gateway A (or Gateway B), and input the IP address of Gateway B (or Gateway A) to see if there is any response from its peer device. Connect a PC (called PC_A) to the LAN port of Gateway A, and connect another PC (called PC_B) to the LAN port of Gateway B. Start to “Ping” PC_B on PC_A, then Gateway A will start to establish IPSec connection with Gateway B. If you can get “Ping” responses from PC_B on PC_A, then it means the tunnel has been established successfully. You can also check the “VPN Status” page with web management interface to verify the status of VPN connections. Figure 1: VPN status of Gateway A after IPSec connection has been established. Figure 2: VPN status of Gateway B after IPSec connection has been established.
Hope this helps

Unable to get remote desk top computer to work on acer aspire one


I think you're trying to connect to your office computer from home/somewhere else.

If that's the case, make sure you have done the following :
  1. Your VPN Session is connected
  2. Your Office IT Administrator allowed RDC over VPN
  3. Your Office Computer RDC is enabled
  4. Your User (local or domain user) having administrative rights or allowed to connect to RDC session
  5. You got no firewall blocking RDC connection or remote registry
To check if you already connected to your office VPN, launch command prompt and try pinging your office computer name or IP Address. As an example if your office computer name is PC-100 and IP address is 192.168.1.100 then you will issue : ping PC-100 or ping 192.168.1.100. If you got ping reply than you're good to go.

To Enable RDC on your office computer there are 2 ways :
1. On your office computer, right click my computer > properties > Remote > Enable Remote Desktop
2. Via remote registry :
- Start > Run > Regedit > Enter/Return
- On registry editor, go to File > Connect Network Registry > Type in your office computer name > OK
- On your office computer registry, browse to : HKEY_LOCAL_MACHINE\System\CurrentControlSet\Control\Terminal Server, find the key "fDenyTSConnections", double click it and change the value to 0

You should disable your windows firewall or 3rd party firewall for easier configuration. You can;however set up exception on your firewall but will need some knowledge to do that.

Hope it helps.

VPN


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.
