Sophos UTM 9 get to offline

tetta
Hi everyone, Im newbie here. A few days ago after years of using astaro I upgrade my firewall to sophos UTM 9. I realized that after some time of users inactivity (not browsing the net) sophos get to some "offline phase", and I cant get to internet nor to internal NAS. Ping is OK, DHCP is working but I cant make RDP to other PC into LAN neither browse the web. Any ideas how to repair that? thanks,

    Tetta, can you reach the Webadmin from another interface on the box?  What kind of NICs are you using?

    I have atom motherboard with two NIC integrated, I use both of them , one for internal, other for external link. From internal I cannot reach admin site. That the problem too, yes.
    But if I restart PC , it works well.. dont have any idea.

    Again what kind of NICs are they?  Intel NICs?  I need to know the chipset.

    Yes intel NIC (Intel NM10 Chipset )

    If they are Intel NICs (using the E1000E driver), check the kernel log around the time you lose connectivity for something that looks like this:

    (the key part is the "Reset adapter" part at the end) ... 

    If all of the above applies, then it might be a "rare" issue with the Intel NIC driver in UTM V9.  I have had 1 customer that has had this issue, and the fix for it won't be available unti UTM 9.005 is released.  The answer in the one case I've had with this is to roll back (in his case) to older hardware with V8 on it... if your system has been working OK with V8, just go back to that for a bit until 9.005 is released.

    It is rare .. out of many customers, only this one customer of mine (out of about 50 with UTMs) had the issue.

    FWIW, when he lost connectivity, and I looked at it from the outside (Internet) the internal NIC showed as Link Down ... like it was unplugged, at least as far as Webadmin was concerned. That's another tell-tale sign of the issue.

    Of course, check all the other things, speed and duplex settings, etc. before jumping to conclusions.
