Have Pepwave MAX HD2 running firmware v 6.1.0.
I have 2 x embedded SIMS - Cellular 1 & 2 interfaces
I have 2 x external cellular routers on WAN1 & WAN2
WAN1 & 2 sims are not fixed public IP addresses. So WAN1&2 lan subnets are different to Pepwave LAN subnet.
No issues with data connectivity.
However I added static routes in Network-LAN-Basic Settings-static route settings to allow access from the pepwave LAN across to the 2 x other LANs.
They seem only to work sporadically. At present I can ping / access via web broser the router for one of the lANs, but not the other. The rules are similar for both - i.e the rule is same format, but different LAN subnet and gateway.
