Problem with ESXI 6 and UTM

RChadwick

I've been running Sophos UTM in an ESXi 5.5 VM for a while with no problems. I need to move to a new server. The new server has ESXi 6u2, and I copied the VM over, configured the network cards (Configured as E1000), and fired it up. Everything seems to work fine, except I seem to be dropping packets. If I run an extended ping to google.com, there are a number of 'Unreachable's, Going to websites sometimes works, and sometimes hangs a long time. Is there a setting in Sophos I need to change? Or is the problem in ESXi?

    I would use vmxnet3 interfaces rather than e1000.  Is this ping from a client behind the UTM or from the UTM itself?

    Thanks for the response!

    Oddly, that wasn't one of the choices. I could only select E1000 or Flexible (If I recall correctly). No choice for vmxnet3.

    The ping was from a laptop connected to the network LAN, connecting out to a server on the WAN (Google.com). Oddly, I saw a few dropouts after switching back to my old server/UTM, but websites are MUCH faster loading, and are no longer hanging like the new server was.

     

    On a related tangent:

    Since I had previous problems with the first version of ESXi 6 (In addition to the packet loss thing, my drives would disappear after a few hours, and needed to reboot the ESXI server to bring them back), my confidence in ESXi is dropping fast. What are thoughts on moving to a free Xenserver instance? I saw that Citrix Enterprise is supported, not sure if the free version will work with UTM. Is Xen supported? Reliable?

    I have no experience with Xen, but lots with ESXi.  I wonder what kind of hardware you are running ESXi on.  What kind of physical NIC is in the server?  Something is definitely wrong if you cannot select vmxnet3.  What kind of OS did you tell ESXi it was?

    I'm running it on a Dell Poweredge R610, which has 4 built in NICs. Apparently I used 'Other Linux  (32-Bit)'

    You probably should have selected Suse Linux Enterprise 11 (64-bit) assuming you are using the 64-bit install (should be). I would rebuild since you are early in the process.

    Well, I reinstalled, selected Suse, and now I have the option for vmxnet3, which I selected. I restored the configuration into Sophos, and so far everything seems to be working good. I'll watch it for another week or 3 until I migrate my other VM's over.

    Thanks!

    Glad to hear it is working better for you.  Good luck with it!
