If you want something gui driven I’d do something like Meraki…you can do the same with just regular old Cisco routers using DMVPN as well.  It’s a pretty common use case and well established.

Hi folks,

Do you have any recommendations for VPN appliances? Specifically: I need to build a site to site VPNs at speeds between 100mpbs and 1 gbit where all but one of the sites are behind an IPv4 NAT gateway with dynamic public IP addresses.

Normally I'd throw OpenVPN on a couple of Linux boxes and be happy but my customer insists on a network appliance. Site to site VPNs using IPSec and static IP addresses on the plaintext side are a dime a dozen but traversing NAT and dynamic IP addresses (and automatically re-establishing when the service goes out and comes back up with different addresses) is a hard requirement.

Thanks in advance,
Bill Herrin
