Wehave a remote working using Global VPN client, and when the VPN is connected internet access is dead slow. The user is very remote so the tunnel itself is quite slow and i accept there is bandwidth limitations. That said, Ive made sure ive set the Set Default Route as this Gateway unchecked so that the remote user is using their local gateway route which i can confirm is working. But i think the issue is more related to DNS queries which is happening over the link as the DNS server assigned by the VPN DHCP pool is at the VPN end.
I will need to send some DNS queries over the link (ones intended for the local domain) but ideally other DNS queries would use the locally assigned DNS server for the remote user. Im thinking a dirty hack for this one person would be to throw some hosts entries into the local PC but i cant workout how to set static IP address for this specific client the global VPN client so that i can use a different DNS server.
ok think i might have come up with something. On the global VPN adaptor on the PC ive just set fixed DNS Servers (left IP dynamic) and set 8.8.8.8 as primary and corporate as secondary. Think that should do the trick. Or any other better ideas?
So thats helped DNS resolutions, but its clear that the downloads are still coming via the tunnel, but uploads are using the local gateway. See attached screen shots of speedtest with VPN ON and OFF. Also status page showing default traffic tunnelled to peer is disabled. Any ideas?
Hi. I do, but the issue is the other clients internet speed and throughput to the remote end is the same, so there is no difference in speedtest results. I will ask the client to try to hot spot on their phone as that will have a different subnet as the remote end.
You must the change GVC VPN interface ip adress. This configuration isn't correct. Remote user network ip and Sonicwall VPN subnet must be different. after change the vpn interface ip address, problem will be resolve.
I have tried all the ideas that I have come across including turning nat traversal on and off. Have tried using the sonicwall dhcp server and the network dhcp server. Have created a new policy, and no change. If I turn off the virtual IP address I am able to connect just fine. I need the vpn clients to be able to reach other machines in the domain though, so I need the virtual ip. I am completely at a loss at this point and it is looking like this is going to eat up my weekend.
In your description it is a bit confusing, where you say:"If I turn off the virtual IP address I am able to connect just fine. I need the vpn clients to be able to reach other machines in the domain though, so I need the virtual ip."
Even though you already know how to set up the Sonicwall, since there is a problem it could be prudent for you to review the process for setting up.Here is a site that may be a different description and so may provide an alternate viewpoint:

The other main consideration is to give the user access to the office Lan. My Office LAN network is defined as the "Lan Subnet" in the sonicwall.Under Local Users (in the case of no AD integration), make sure the User is allowed access to "Lan Subnets" in my case.
The only thing keeping me from blowing away the crappy Vista install on my Toshiba laptop and going pure Ubuntu is the fact that I need to VPN to work and they use Sonicwall. Due to some proprietary voodoo used by that particular firewall setup on my work's end, I have to use the Sonicwall client which only runs on Windows.
Yes, there is a Sonicwall NetExtender client that is available for download from sonicwalls website. I use it all the time. Once installed just type netExtender (case sensitive) from the command line and you will be prompted for your creds.
I too, the same stage now. I did'nt tried OpenSwan VPN. How ever net extender won't help in my case. As per my knowledge we have to configure NetExtender in sonicwall device in-order to use NetExtender client
There is an official knowledge base article from SonicWall here that goes through the steps for Linux installation. They discuss both GUI and command line usage of the netExtender program once installed. The later is nice because you won't have to install additional Java dependencies for the GUI
Businesses large and small need to address the growing demands of more distributed work sites and an increasingly mobile workforce in order to compete in today's global marketplace. Remote access has become a business imperative.
SonicWall VPN Clients offer a flexible easy-to-use, easy-to-manage Virtual Private Network (VPN) solution that provides distributed and mobile users with secure, reliable remote access to corporate assets via broadband, wireless and dial-up connections. For remote client-to-host secure access, SonicWall offers both SSL VPN and IPSec VPN connectivity options. For SSL VPN, SonicWall NetExtender provides thin client connectivity and clientless Web-based remote access for Windows, Windows Mobile, Mac and Linux-based systems. For IPSec VPN, SonicWall Global VPN Client enables the client system to download the VPN client for a more traditional client-based VPN experience.
Give your employees safe, easy access to the data and resources they need to be productive from a range of devices, including iOS, OS X, Android, Chrome OS, Kindle Fire and Windows. At the same time, ensure that your corporate network is protected from unauthorised access and mobile security threats.
Enhanced layered security is enabled when a SonicWall Network Security Appliance uses powerful deep packet inspection technology to scan VPN traffic for malicious threats such as viruses, worms, Trojans and spyware. The combined solution is known as SonicWall Clean VPN*.
Behind the scenes, IT can easily provision and manage access policies via SonicWall appliances through a single management interface, including restricting VPN access to a set of trusted mobile apps allowed by the administrator. Plus, the SonicWall solution integrates easily with most back-end authentication systems, including two-factor authentication, so you can efficiently extend your preferred authentication practices to your mobile workers.
Centralized policy management
IT can provision and manage mobile device access via SonicWall appliances - including control of all web resources, file shares and client-server resources - through a single management interface. Unlike other VPN solutions, the SonicWall solution allows you to quickly set rolebased policy for mobile and laptop devices and users with a single rule across all objects; as a result, policy management can take only minutes instead of hours.
Verification of both user and device
A Mobile Connect user is granted access to the corporate network only after the user has been authenticated and mobile device integrity has been verified. End Point Control can determine whether an iOS device has been jailbroken or an Android device has been rooted, as well as whether a certificate is present or the OS version is current, and then reject or quarantine the connection as appropriate.
Easy access to appropriate resources
iOS, Android, Chrome OS, Kindle and Windows mobile devices can connect to all allowed network resources, including web-based, client/server, server-based, host-based and back-connect applications. Once a user and device are verified, Mobile Connect offers pre-configured bookmarks for one-click access to corporate applications and resources for which the user and device has privileges.
Mobile device registration and authorization policy management
With Mobile Connect and Secure Mobile Access OS (versions 11.0 and above) for Secure Mobile Access 1000 Series appliances, prior to granting network access, if a mobile device has not previously registered with the SMA appliance, the user is presented with a device authorization policy for acceptance. The user must accept the terms of the policy to register the device and gain access to allowed corporate resources and data. The terms of the policy are customizable by the administrator.
Per-application VPN
Mobile Connect in combination with Secure Mobile Access OS (versions 11.0 and above) for Secure Mobile Access 1000 Series appliances, enables administrators to establish and enforce policies to designate which apps on a mobile device can be granted VPN access to the network. This ensures that only authorised mobile business apps utilize VPN access. Mobile Connect is the only solution that requires no modification of mobile apps for per app VPN access. Any mobile app or secure container can be supported with no modifications, app wrapping or SDK development.
Auto-launch VPN
URL control allows apps that require a VPN connection for business (including Safari) to create a VPN profile and automatically initiate or disconnect Mobile Connect on launch (requires compatible server firmware). In addition, for iOS or OS X devices, to simplify use when a secure connection is required, VPN on Demand automatically initiates a secure SSL VPN session when a user requests internal data, applications, websites or hosts.
Integration with existing authentication solutions
The SonicWall solution supports easy integration with most back-end authentication systems, such as LDAP, Active Directory and Radius, so you can efficiently extend your preferred authentication practices to your mobile workers. For increased security, you can enable one-time password generation and easily integrate with two-factor authentication technologies.
The user experience is similar to that of a traditional IPSec VPN client, except that manual client installation is not required. Additionally, users do not have to worry about Network Address Translation (NAT) devices and proxies, which are the bane of traditional IPSec-based VPNs.
NetExtender creates a virtual adapter for secure point-to-point access to any allowed host or subnet on the internal network. Unlike the stateless nature of the traditional SSL VPN, NetExtender stays resident on the client machine even after the connection is closed.
