The last firmware update 18.104.22.168 that was applied to this modem basically stops my connection using Sonicwall VPN. Looking at the sonicwall log, this is the one that I'm having:
|2016/06/16 10:27:27:592||Information||X.X.X.X||Starting ISAKMP phase 1 negotiation.|
|2016/06/16 10:27:45:058||Error||X.X.X.X||An error occurred.|
|2016/06/16 10:27:45:058||Error||X.X.X.X||The peer is not responding to phase 1 ISAKMP requests.|
Did a basic trouble shooting using the same laptop but internet connection is tethered thru my mobile phone and everything work fine. Also turn off the firewall on the modem, restart and still giving me the same issue. Can anyone suggest a fix for this.
