One of the router at the remote office is connected to my office in London. The VPN connection from remote office to london keeps on disconnecting and cannot reconnect unless the connection is forced on the router or router is rebooted. A new router is sent to the remote office but the problem persists. The router we have is cisco 1811. <br />
<br />
I am asked to investigate the possible problems with it. <br />
<br />
Can any one help??

VPN connection keeps on disconnecting and not reconnecting.

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.

Network Operations includes asset management, help-desk supervision, security and user policies, infrastructure administration and anything else that affects the operation of your network. Discussions will include those of best practices in platforms, configurations, performance, security and accounting.
