I have an OpenWRT box set up on my network that dials up via 3G and then launches an OpenVPN connection to a remote server. The idea of this is so that if something goes wrong with the main router I can connect to the remote server, back through the OpenVPN connection and onto the network. The reason for the OpenVPN connection is that the 3G connection doesn't have a static IP and is also NAT'd by the carrier so isn't externally accessible even if I knew the external IP (eg dyndns wouldn't help me). At some point in the last few weeks it has stopped working though. The last thing I see in the logs when it tries to connect is: Dec 16 15:19:32 bitgw2 local2.info chat[7031]: ATD*99***1#^M^M Dec 16 15:19:32 bitgw2 local2.info chat[7031]: NO CARRIER Dec 16 15:19:32 bitgw2 local2.info chat[7031]: -- failed Dec 16 15:19:32 bitgw2 local2.info chat[7031]: Failed (NO CARRIER) Dec 16 15:19:32 bitgw2 daemon.err pppd[7027]: Connect script failed Dec 16 15:19:33 bitgw2 daemon.info pppd[7027]: Exit. gcom says: Trying list of devices SIM ready Waiting for Registration..(120 sec max) Registered on Home network: "50502",2 Signal Quality: 24,99 Which afaict means that the modem is talking to the base station and that there is some signal available. The next thing I would suspect is the 3G account with the carrier is closed or otherwise broken... is that consistent with a NO CARRIER response or should the modem give some other response? I'm not the account holder so I can't contact the carrier until tomorrow. This was working just fine and nothing has changed so I assume it's an external factor... Is there a command I can send to the modem to find more information? Thanks James
