Failover 4G will not run VPN (Client VPN)

[AnthonyMaddick]

Hi I have an MX68 and it is running fine on the primary link with VPN but when the primary link fails the VPN will not connect through the 4G fail over (telstra).

The 4G modem (teltonika RUT240) connected to WAN2 has all its defaults set with no open ports. 

Can the telstra connection be blocking it?

Thanks in advance

You'll need to find an APN for your 4G carrier that will provide a public IP address and no firewalling.  It certainly won't be the default APN.

Google has suggest the APN is:

telstra.extranet
