I found a Huawei E220 3g/UMTS modem (which saw it is compatible with sophos) and decided to give a try as a failover solution.
I plugged it on a spare port and after a reboot (well, 2 reboots, actually), the UTM detected it and I managed to add it as a standby interface.
I saw that the interface was appearing down. I disabled the primary wan interface and after a while the 3g changed its state to UP and was actually showing 3 bars of signal. However I was not able to access the internet.
[LIST=1]
- Is there anything else to configure? Does the appearance of the signal bars mean that it has internet connection?
- Is there a way to actually verify that this interface connects to the ISP and internet connection is available? Any logs that I can see, or any commands to run via ssh?
Thanks a lot in advance, guys!!!
