Issue was on the ISP side....connection is pegged...

<div>
<div class="content wysiwyg-content">
I currently have a site to site VPN using two ISP's (Geographic separations) and I am seeing very large latency across when I run pings across it (300-500ms) &nbsp;I understand the internet is best effort, but this is unusually high....on the network pings are returned 12-15ms...its just when they are initiated across the VPN that I see the high returns....I am running 3DES, and was wondering if going to 128 AES would alleviate the strain, or if I should check with the ISP's as well?

VPN Latency Issues

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.
