<p><font face="Arial" size="2"><span style="font-size: 10pt; font-family: Arial;">I would like to setup VPN connection between 2 offices in
two different countries. Say, Office A is connected to ISP A at country A, and
Office B is connected to ISP B at country B. We would like to have VPN
connection between Office A and Office B. The application will be: sharing
files (data), voice, and video conferencing between the two offices. We are
going to use Cisco 2801 for this application. I have searched for support
document on how to configure 2801 for VPN connection and Voice gateway, but the
document available is limited. Please suggest how I can configure the two
routers to achieve the goal. Your help will be much appreciated.</span></font></p>
