it is difficult to understand how to use the TBR140 using standard SIM cards without static public IP or DynDNS. The main issue is the local and remote identifier that should be an IP or FQDN. I used just a private hostname e.g. likeabird.fusionhub as local id and likeabird.tbr140 as remote id. I was able to connect between the TBR140 and FusionHub, however other PepVPNs was dropped.
The Fusionhub has a WAN 10.0.0.0 subnet and a LAN subnet 10.0.1.0.
What is missing is a Fusionhub IPsec examples using the Fusionhub and a non static IP remote LTE router.
