[Christos Mourouzis]

Hello Jeff,

Thanks for the reply. I opened a case on the multitech support as you suggested. I managed to have some progress on my issue. Maybe someone could help with the following:

I changed the location of the gateway and I managed to get connected to the APN but I have a modem hangup (SIGHUP).

I need the instructions for authenticating my sim card (Simfony) because it requires a username and a password.

In the log file I get:

Even if edit /etc/ppp/pap-secrets or /etc/ppp/chap-secrets file with the correct username and password I can’t manage to get a successful connection.

Can someone please provide me the instructions for having a ppp connection with authentication?

Thank you very much!

Thanks to both for your answers. I also tried your suggestions. Now I have, cellular and “dial-on-demand” enabled. In WAN settings, ethernet is in Active Failover Monitoring mode for every 60s-ICMP with priority equal to 1 and cellular is in Passive Failover Monitoring mode with priority equal to 2. The gateway is connected to ethernet for sure and has a valid SIM card installed.

The problem is that when I save and restart the cellular connection is started first and then switches to ethernet. Then instead of closing the cellular connection, the gateway has both enabled and running the ethernet and cellular connections (WAN Transport=Ethernet and PPP link is up).

If i “ifconfig eth0” and “ifconfig ppp0” in the terminal (ssh to gateway) I can see much bigger traffic in ethernet but cellular still has increasing traffic (RX and TX packets).

I can’t understand why the cellular connection starts first. If ethernet started then I guess, cellular would be down due to the “dial-on-command”.

Do you have any more suggestions to do or try?

Best,

Christos
