Forgive my ignorance here,
I've got an edgerouter and a USG onsite. 2 ISP:
ISP 1 & 2 are connected to the edgerouter, which serves the LAN in failover mode.
A second IP from ISP 2 is connected to the USG, which currently serves absolutely nothing.
Offsite, I have another USG which I'd like to configure a site-to-site VPN to the local USG with. The question becomes, how do I connect the local USG to the existing EdgeRouter LAN, such that offsite network can access all the local resources (behind the EdgeRouter)?
I know that I could configure an Edgerouter-to-USG site-to-site, but I'd like to try and utilize the USG simplicity of GUI for the operation without having to get into CLI - not only for the easy site-to-site config, but also for everything else (device provisioning throught he controller, port forwarding, etc.). It's just soooo much easier for a noob like me to work in the USG controller than it is to configure Edgemax. Crossing my fingers that there's a simple way to do this.
Thanks!
