suggest you use a different IP subnet for DHCP over VPN<br />
<br />
create a new DHCP pool, but do not assign it to an interface, e.g. 192.168.254.60-99<br />
<br />
then on DHCP over VPN set the relay IP to an IP address of that subnet but not in the scope.<br />
e.g.. 182.168.254.254

Hey Guys, currently we have the VPN just using the same DHCP scope as other users. For now we have resolved the issue by disabling auto-reconnect on the VPN client, but I will try and implement your suggestions as well. <br />
<br />
Thanks!

Our users keep leaving the VPN connections on their laptops active. This means when they arrive at work and connect to the network DHCP completely breaks and goes into a death-spiral of assigning bad addresses. <br />
<br />
Any ideas on how I could prevent this from happening in the future? (We are using Sonicwall's GlobalVPN client).

Our users are leaving their VPNs connected and then breaking DHCP when they connect to the network locally.

Networking is the process of connecting computing devices, peripherals and terminals together through a system that uses wiring, cabling or radio waves that enable their users to communicate, share information and interact over distances. Often associated are issues regarding operating systems, hardware and equipment, cloud and virtual networking, protocols, architecture, storage and management.

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.

A laptop or notebook is a portable personal computer with a clamshell form factor, suitable for mobile use. Although originally there was a distinction between laptops and notebooks, the former being bigger and heavier than the latter, there is often no longer any difference. Laptops are commonly used in a variety of settings, such as at work, in education, and for personal multimedia. A laptop combines the components, inputs, outputs and capabilities of a desktop computer, including the display screen, speakers, a keyboard, and pointing devices (such as a touchpad or trackpad) into a single unit. The device can be powered either from a rechargeable battery or by mains electricity from an AC adapter.
