The default profile on the B315 comes configured as 'Broadband'. Connections out from the router work fine, but am unable to ping or connect on other ports from any other internet address. All firewall and port pinhole settings on the B315 to allow traffic through on the VPN port I'm using appear correctly configured, but just will not work, so have concluded that the Broadband APN blocks traffic from the net, just as other standard APNs do.
Changing the Profile to use 'direct' or 'connect' or 'internet' just kills the 4G connection, so they're obviously not set up for 4G addresses (I'm seeing 100.xx.xx.xx addresses assigned).
Am hoping there is an equivalent of 'direct' for 4G, otherwise will have to cancel the service and find another provider that can allow opening these connections.
TIA.
