I have an Edge Router as well. I know this particular thread is about IPSec but wanted to mention that the OpenVPN version on EdgeOS is rather old at this point and fairly underperformant for anyone considering that route.
Thanks for the info. This vpn setup for me maxes out at 25Mbps but that's only because my ISP caps my upload at that. I bet the pi 3 can do 100Mbps of Cisco IPsec traffic maxing out the ethernet 100BASE-T interface.
