First I apologize for the basic question but somehow is am still missing a basic configuration for the drop-in mode. I am using Balance 20X with an ISP as primary and an internal SIM card.
I have an ISP with a single IP 157.130.###.###, connected to a Linksys Router.
My internal IP gateway is 10.189.154.134, subnet 255.255.255.0
My setting in Peplink for drop-in shared IP are
Shared IP Address: 157.130.###.###
Static Route: Blank
WAN default Gateway: 10.189.154.134
DNS Servers: 8.8.8.8 & 8.8.4.4
Thanks for the help
Brad
