VPN Connection Between two USG60s Behind an ISP Modem
Hi, I have a different situation that I haven't ran into in the past and am wondering if someone can help me out.
I want to do a VPN connection with two USG60s so that Site A and Site B can access the same file server that is hosted on Site A. The problem I'm running into is that Site A's USG60 needs to be connected behind a Google Fiber network box due to a system that needs to be segregated off of the USG60 so the USG60 has a Lan address 192.168.2.x instead of a WAN address. Site B's USG60 can be connected right into the WAN and pulls a public IP. I've attached a diagram that may explain my situation better.
My initial thought was to have Site A establish the connection to Site B in a host/client setup, but I am not sure how to do that. I've only set up zyxel equipment in a Point to Point connection with two WAN addresses outlined here: https://businessforum.zyxel.com/discussion/551/an-example-of-site-to-site-vpn
