VPN on PEPWAVE On The Go

I have 2 PEPWAVE MAX-OTG-U4-SF and need stabilish VPN between them. Can I do this directly or I need a PepBalance to made this connection?

You can do this directly between the two MAX-OTG’s, just make sure you are running on current firmware.

Nice.
I’m running 6.1 and updated today, but VPN no run Up yet.
Should I use IPsec VPN or Speed Fusion?
I have some doubts in VPN profile, could You help me with a example?
I need to fill speedfusion with all IP nodes, right?

(Router1)—>(USB WAN)----->(Internet)<----(USB WAN)<----(Router2)
10.1.1.1 <-------------------------------------------------> 10.1.2.1

My traceRT:
10.1.1.1 Router 1
192.168.0.1 Gateway
10.170.80.68 Node NAT
177.79.245.148 Public IP
201.7.186.46 Public IP
10.1.2.1 Node

You should use SpeedFusion, and at least one side needs to have a publically routable address.
