Internet Dropping every 4 hours

Question

We have been struggling with an issue for several days now.

Every 4 hours, we lose Internet connectivity, generally for 10 minutes. After those 10 minutes it comes back up. Email is still going through, but any web traffic stops.

We have tried everything we can think of, such as turning off the auto updates, disabling the filtering, but nothing seems to work.

I am wondering if anyone else has experienced anything similar and, if so, how you addressed it.

We are running Sophos UTM 9 with firmware version 9.312-8 (the problem started before we installed the latest update, but after we had installed the previous one). Otherwise, as far as we know, nothing has changed.

It worked fine Sunday. It did not on Monday.

Thanks,
John

Hi, John, and welcome to the User BB as a poster!

It does sound like you got a bad Up2Date. I would be tempted to re-install these Up2Dates using the "version change" trick - you might get lucky.

In the following, you can copy and paste each block of code - no need to do a line at a time:
[LIST=1]In WebAdmin, on the 'Configuration' tab of 'Management >> Up2Date', set 'Firmware download interval' to "Manual."

At the command line as root, make sure you're in the correct directory!
```
cd /var/up2date/sys
```
Delete any existing Up2Date files and download the two packages from the ftp site: from the command line as root:
```
rm*

wget ftp.astaro.com/.../u2d-sys-9.310011-311003.tgz.gpg

wget ftp.astaro.com/.../u2d-sys-9.311003-312008.tgz.gpg
```
Confirm that each md5sum is correct by comparing the results of the following with the contents of the corresponding .md5 files at ftp://ftp.astaro.com/pub/UTM/v9/up2date:
```
md5sum u2d-sys-9.310011-311003.tgz.gpg

md5sum u2d-sys-9.311003-312008.tgz.gpg
```
If there was any error in any file, rm that file and download again as in step 3.
Do the "version change" trick:
```
echo ' 9.310011'>/etc/version
```
Prepare the Up2Dates for installation in WebAdmin:
```
/sbin/auisys.plx --showdesc
```
Install in WebAdmin on the 'Overview' tab of 'Management >> Up2Date'. Afterwards, remember to set your 'Firmware download interval' back to what you want.

Did that cure the problem? If not, you're probably stuck with backing up, reloading from ISO and restoring from the configuration backup.
