This configuration looks good for IPSec pass through, but you'll need to permit GRE inbound on your 110 ACL in order to get PPTP pass through to work.

Thank you, the combination of the access-list and NAT worked for both VPN clients.

We have a Cisco 881 router that is blocking our contractors from using their VPN's (both Cisco IPsec and Microsoft PPTP) connections back to their offices. I have attached a configuration file to help.

Cisco 881 router allow outbound VPN for PPTP and IPSec

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.

Web Components are a set of standards currently being produced by Google engineers as a W3C specification that allow for the creation of reusable widgets or components in web documents and web applications. The intention behind them is to bring component-based software engineering to the World Wide Web. The components model allows for encapsulation and interoperability of individual HTML elements. Support for Web Components is present in Chrome and Opera and is in Firefox (with a manual configuration change). Microsoft's Internet Explorer has not implemented any Web Components specifications yet. Web Components consist of 4 main elements: Custom Elements, Shadow DOM, HTML Imports and HTML Templates.
