Internal connectivity issues since SG125 was replaced (Was 9.350, now 9.502)

ThomasBall

Had a box fail and it was replaced with a new unit.

Used a USB backup to restore setting to the new unit.

 

Since that time there have been client to server connectivity issues on the LAN have failed.

However the traffic does not pass through the box so I ma thinking it may be a DHCP or DNS issue.

(File serving is fine it is just remote database/ accounting applications that are failing (Traverse and Sage).

 

The only concern was the 9.350 backup being applied to the new 9.502 box.

 

Any tips on how to troubleshoot/reset the previous settings?

    It is 9.505 not 3.505 or 3.350, correct?

    You could try to image your new hardware to the old version and then restore your backup.

    May I ask why you were using such an old version?

    Best

    PS tell us a little more about your settings, proxy, ssl scan and network topology.

    Thanks for the response Alex.

    (Sorry, I will correct the 3. to 9.)

     

    The unit had filled up the root partition and would not allow any access, so was stuck on 9.350.

    I asked for the replacement to be imaged to this version but was sent as 9.502 (correction from original post)

    (The unit is at a remote location so there are limited options)

     

    Very basic setup...

    WAN port to ADSL modem (Transparent proxy)

    LAN port to single switch for network (10.0.7.0) (Including Windows Server with DHCP static ip, all rest machines DHCP)

    VPN to second office SG125 (10.0.6.0)

    Hi Tom,

    ok, as there only specific applications (remote) are failing I assume these are related to the transparent proxy. Are you using SSL scan? Maybe try to turn it off, just for a test.

    As second guess look in the firewall log, anything related?

    The failing applications are on a server on the LAN, as are the workstations.

    Thus in theory none of this traffic should be going through the proxy?

    I see nothing in the logs.

    Might it just be a coincidence and show some other network issue caused by another device?

    Solved!

    (The onsite tech found this)

     

    Seems that the new MAC of the gateway triggered the Microsoft server to spin up a new public network instead of the previous private.

    This allowed some services through the firewall and blocked the really important ones!

    So it had nothing to do with the restore version but the hardware change was "responsible".

    (Thus all assumptions were correct)

     

    I just love how helpful Microsoft has become!

     

    Thanks for the feedback.
