Need a Public IP address on the Cellular modem for Remote access of a NAS on a LAN behind Peplink BalanceOne. No load balancing. No automatic switching between working or not working connections. No switching based on Speeds or bandwidth.
Strictly a case of user being able to choose to use Main Connection or Alternate Connection to Remotely access the NAS. The Satellite connection is too slow for some usage Remote Downloads (Satellite Uploads). Whereas, Cellular connection is far to expensive for general remote usage.
Below is rough layout of Remote / WWW / WAN / LAN access
Where yyy:yyy:yyy:yyy is Persistent Public IP Address
Where xxx:xxx:xxx:xxx is Persistent or Static Public IP Address
Main Access: Remote Location <— Internet —> yyy:yyy:yyy:yyy Satellite Modem <–> WAN#1 of BalanceOne <-- LAN --> Port#1 NAS
Alter Access: Remote Location <— Internet —> xxx:xxx:xxx:xxx Cellular Modem <–> USB of BalanceOne <-- LAN --> Port#2 NAS
What has been tried - but fails with BalanceOne
Main Access: Remote Location <— Internet —> yyy:yyy:yyy:yyy Satellite Modem <–> WAN#1 BalanceOne <-- LAN --> Port#1 NAS
Alter Access: Remote Location <— Internet —> xxx:xxx:xxx:xxx Cellular Modem - MoFi-4500 Router** <–> WAN#2 of BalanceOne <-- LAN --> Port#2 NAS
***MoFi Router is used to provide a Cloud-VPN assigned Static Public IP Address. *
However, the MoFi and BalanceOne so far have not worked together. Appears to be an issue with MoFi trying to do Routing and Firewalling .vs. working like a the Satellite Modem (no routing, no firewalls - basic passthrough with NAT & DHCP information).
All attempts at setting up Port Forwarding on BalanceOne – along with Port Forwarding on MoFi, setting BalanceOne (or the NAZ) in a DMZ on MoFi, enabling IP Passthrough on MoFi, and turning off Firewall on MoFi router have failed.
The MoFi router works quite well when used by itself, in place of BalanceOne as a router. Problem comes when connecting Satellite to WAN port of MoFi router. The MoFi router will only allow Cellular Access if the Satellite connection is Down (or manually Disabled). An Exclusive OR situation.
Thus need to look at using Cellular Modem connected directly to USB port of BalanceOne and coming up with a Persistent or Static Public IP Address to remotely access the Cellular Modem.
