Why use PPTP and not the SonicWALL's IPsec or SSL-VPN capabilities? it's way more secure to do it on the gateway<br />
<br />
For a 24/7 it's more advised to use a Site-to-Site VPN tunnel<br />
<br />
<br />

<br />
Multiply the effectiveness of your APT Sandbox, stop unknown and zero-day attacks at the gateway. See a demo on <a href="http://apt-demo.com" rel="ugc">http://apt-demo.com</a>&nbsp;or <a href="http://atp.demo.com" rel="ugc">http://atp.demo.com</a><br />

<div>
there are already site to site vpn established with other offices using sonicwall and this particular client office provides only pptp vpn. they don't have sonicwall devices in their network
</div>


<div>
Still much more handy to continue site to stie. You can even use a lower priced router (Draytek Vigor) for this issue (though some are limited to only 2 lan-to-lan profiles).
</div>


<div>
strongly advise to replace the box then. PPTP is unencrypted and insecure, also by doing PPTP through the firewall on your end, you can't inspect the traffic...
</div>


<div>
Infact this scenario need to be enabled for a testing purpose, where the client won't allow any other form of vpn environment other than PPTP. <br />
<br />
I found a link which describes the vpn sharing<br />
<a href="https://www.securitykiss.com/resources/tutorials/shared_vpn/windows/" rel="ugc">https://www.securitykiss.com/resources/tutorials/shared_vpn/windows/</a><br />
<br />
I will try this and update you.
</div>


<div>
The solution from your link is useful if you dedicate one PC as a router. Obviously, you need the current router device already, meaning you will now have Internet &gt;&nbsp;modem/router &gt;&nbsp;PC with VPN sharing (2 LAN cards) &gt;&nbsp;LAN <br />
It means, you will complicate the whole network quite a bit.<br />
If you are really firm on only using PPTP and sharing it, replace the router with the aforementioned Draytek Vigor series, not only do they support the easy to setup IPSEC Lan-to-Lan, it also has PPTP dial out profiles.
</div>


<div>
If you are stuck on using PPTP, make sure the PPTP terminator is in a &nbsp;DMZ zone of your firewall and not straight in your lan
</div>


<div>
That may work, but you need two NICs. A better way is to use Routing and Remote Access for that.<br />
On a server OS it is very easy to set up; just add the interface in the NAT section as private without using an address pool.<br />
On a client OS it is more tricky as you cannot access RRAS via GUI. I've written an (old) article to that regard: <a href="https://www.experts-exchange.com/articles/350/Using-remote-client-connections-VPN-ISDN-PPTP-aso-for-routing-in-Windows.html" rel="ugc">https://www.experts-exchange.com/articles/350/Using-remote-client-connections-VPN-ISDN-PPTP-aso-for-routing-in-Windows.html</a>&nbsp;which should stil work for recent client OS.

I have a scenario where my office need to connect to another client office vpn using pptp. My office is connected to internet via router and a sonicwall firewall. Say PC1 in my office in the LAN will dial to client server and establish the vpn. This PC1 will be connected 24/7 VPN with client. Now my question how can I allow other PCs (say for eg PC2 and PC3) on the LAN to share the vpn on PC1 whenever they needed it to access the client server. Also while accessing the VPN the Local access as well as the internet should not be disconnected.

Sharing a PPTP vpn on LAN

Windows Server 2008 and Windows Server 2008 R2, based on the Microsoft Vista codebase, is the last 32-bit server operating system released by Microsoft. It has a number of versions, including including Foundation, Standard, Enterprise, Datacenter, Web, HPC Server, Itanium and Storage; new features included server core installation and Hyper-V.

Windows Server 2008

Hardware-based firewalls provide more sophisticated protection for inbound and outbound traffic than the simple Windows software firewall or the basic NAT firewalls found in routers. These devices implement techniques such as stateful packet inspection, deep packet inspection, and content filtering; and may include built-in antivirus and anti-malware protection.

Hardware Firewalls

Networking hardware includes the physical devices facilitating the use of a computer network. Typically, networking hardware includes gateways, routers, network bridges, modems, wireless access points, networking cables, line drivers, switches, hubs, and repeaters. But it also includes hybrid network devices such as multilayer switches, protocol converters, bridge routers, proxy servers, firewalls, network address translators, multiplexers, network interface controllers, wireless network interface controllers, ISDN terminal adapters and other related hardware.

Networking Hardware-Other

The Windows operating systems have distinct methodologies for designing and implementing networks, and have specific systems to accomplish various networking processes, such as Exchange for email, Sharepoint for shared files and programs, and IIS for delivery of web pages. Microsoft also produces server technologies for networked database use, security and virtualization.

Windows Networking

A virtual private network (VPN) is a network that uses a public telecommunication infrastructure, such as the Internet, to provide remote offices or travelling users access to a central organizational network securely. VPNs encapsulate data transfers using secure cryptographic methods and other security mechanisms to ensure that only authorized users can access the network and that the data cannot be intercepted.
