Does anyone have any experience with running Auto-VPN over 4G connections?
Need a Site-to-Site VPN that can run over a 4G connection at each site.
Both sites do not have Static IP's and can't use DDNS.
Hoping to run a MX67c at each site with a fail over 4G dongle in each running a different 4G network for redundancy.
Any input/help would be greatly appreciated.
Actually after further review I'm not sure how it will work if your using that 4G dongle in addition to the built in. Not sure if you can use both to be honest
Is this SD-WAN over LTE? Can LTE be used as the primary uplink?
No. LTE link can be used as failover or single-uplink only.
So I know you can use the built-in LTE by itself as I have done this. It will work, just not sure what will happen if you try to use that dongle 4G thing your talking about. A backup for the backup etc.
Thanks for the help.
Yeh running external 4G modems is the option I considered with the internal USB as the failover.
Mainly just need to make sure the VPN will work.
Australian 4G providers NAT and share public IP's for 4G services which is why I am keen to know if the cloud based VPN will get around this.
With the MX67C can use use either the built in 4G modem, or an external USB 4G modem, but not both. If you plug in an external USB 4G modem then it disables the internal 4G modem.
If you want to use two 4G modems then the external one will need to be a 4G "hotspot" style, which an Ethernet connection. Then you can plug it into "Internet 1". Note that it will be the primary WAN connection.
