External WAN connection goes down but modem is fine.

BryanEdwards
Hello I am using Sophos UTM9 and have been using it for a few months just fine. Today I was browsing the Internet and suddenly it stopped working. I log onto the web admin page and saw the external WAN connection stat as "down" and link "up" so I assumed the ISP connection had gone down. A couple hours later the Internet is still down so I log onto the Comcast website and the connection status for me is good but the Internet still isn't working. After a couple hours of troubleshooting I discover that the modem is fine and connected but UTM9 is showing a down connection so I can't get online without bypassing UTM and connecting straight to the modem. I can look at the network usage log and see the external connection traffic then all of a sudden nothing. Like I said I have been running just fine for months and haven't configured anything on it in a couple months. I am currently running 9.352-6. Any help will be appreciated and let me know if I need to post any logs.

    Has the issue continued since you resolved the disk space issue? That may have been the root cause of the problem.

    "Did you set the WAN NIC speed/duplex and the modem, too?
    Cheers - Bob"

    I was unable to set the speed in Sophos itself but I did change it on the host. I was unable set the speed on the modem because it's a consumer modem (SB6141). Either way this did not solve the issue.

    "Edit the WAN interface and check off the box for "Set virtual MAC" Type in the MAC of the physical nic used by the Hypervisor host that has the modem ethernet cable plugged into it."

    I set this and it had no affect.

    Since I have created the new VM with the larger provision I have not had any problems with my connection. I am leaning more towards a storage problem on the old UTM because the data disk was pretty much always at 90%+ used space. Is there a way I extend the size of the data and log disk sizes if I provision more space?

    If you know your way around gParted's live disk, then its possible.

    I booted up my VM of the utm and added 16GB to the disk just to see.  

    Sophos multi-partitions the single disk so its going to be a bit of a pain to move partitions around to get the unallocated space to the partition you would like to extend.

    That was it. I provisioned more space to the data and log disk and rebooted UTM and the modem and it started working.
