XG v17.5.4 MR4-1 Released (MR4 update 1)

After updating from 17.5 MR3 to MR4, my UI becames much faster than before... Additionally, in my DHCP Settings, the Option "Use device's DNS settings" was unticked after upgrade... So my DHCP was not delivering any DNS Server Information what caused my clients to not being able to resolve names... 

Anybody else had this issue? I don't know currently what else might be broken with that release...

I presume you upgraded to SFOS xg17.5 MR4-1 (17.5.4.429).   Were you able to "tick" it back ?

My Firewall is currently running on 17.5.4.409. I could go back, but i re-set the option again, and afterwards it worked again.

There is definitely an improvement on the UI performance, very noticeable.

Stupid question like this: Why don’t you upgrade it to 429 ???? Since it fixes a major bug you mentioned earlier ?

Paul Jr

Because if i would do so, and If i would find another "bug", I wouldn't be able to go back to 17.5 MR3.

But you are running 17.5.4 already !!!  And if you did your BU properly, you can always return to MR3 any time.  It is a pain since you would have to wipe your firewall to OEM,  and then re upgrade to 17.5.3 and then import de v17.5.3 MR3 BU file, but is still feasible.

Hello @HuberChristian,

If you have upgraded 17.5 Mr-4-0 before then you may simply roll back to 17.5 Mr-3 and replace the non-active firmware i.e. 17.5 Mr-4-0 with the latest 17.5 Mr-4-1 and perform the upgrade. In case you are encountering any issue with the latest version, you may simply roll back to 17.5 Mr-3. 

Please bear in mind that the backup of the later firmware version will not able to restore on lower firmware.

As a precision.  Let say you see firmwares 17.5.4 MR4-1 (i.e.429) and 17.5.4 MR4 (i.e.409) listed.  And you want to go back to 17.5.3 MR3, you can upload and replace anyone of both firmwares already listed.  For example, in the end, you could have  17.5.4 MR4-1 (i.e.429) and 17.5.3 MR3 (i.e.372) listed. 

Then, once you have replaced the firmware, you get this: 

Obviously, when you revert to 17.5.3 MR3, your appliance will load factory defaults and you will have to upload a 17.5.3 backup.  If you haven't made a BU, you will have to punch all your configuration manually !!!!  Ouch !!! So make sure you have a backup matching the SFOS version you want to restore to.  I'm almost certain you knew that already.

Hello Big_Buck 

The configuration before the upgrade will still remain on your firewall. It should not go back to factory default (unless you have not configured it in Mr-3).

Maybe, but every time I tried, it failed ...  In the case I pictured above, I have manually forced a firmware to replace what was the previous firmware.  I.e. I replaced MR4 with MR3.  MR4 was the previous to MR4-1. MR4-1 remained active, in place, and listed.  So.  I do not believe that while I was uploading MR3, the corresponding configuration came along with it.  So.  In this case, I believe we have to upload MR3 firmware, than we have to upload the MR3 backup.
