From Chimera Computing:
Chimera 'VPNLinkTest' is a program designed specifically for corporate environments who have site-to-site VPN links from a central (hub) site out to remote branch (spoke) sites. It provides a quick and easy way to test whether a VPN link is active and the response of the intermediary devices in its path. It uses ICMP echo requests (or 'pings') to each IP address in the pre-configured path. It reports back on the status and response time of each device, it also provides a visual representation and "plain english" diagnosis based on the results. Specifically developed as a handy time saving utility for IT helpdesk staff.
What's new in this version:
Version 1.1.1 added functionality to add sites from GUI.
