Since 4.3.14, NAT does not work in the guest. I get ""Network unreachable"" when trying using TCP or UDP. ICMP (e.g. ping) works correctly. DNS only works when using host resolver (Otherwise it's also network unreachable for its UDP packets). It does work correctly when using bridged networking. NAT works on 4.3.12, and does not work on 4.3.14, 4.3.16, 4.3.18, 4.3.22 and 4.3.24. Logs are all attached. May it be related to the Sophos Web Intelligence tool? The log shows {{{ 45c.13f8: \Device\HarddiskVolume2\ProgramData\Sophos\Web Intelligence\swi_ifslsp_64.dll: Owner is administrators group. 45c.13f8: supR3HardNtViCallWinVerifyTrust: WinVerifyTrust failed with 0x800b010e (CERT_E_REVOCATION_FAILURE) on '\Device\HarddiskVolume2\ProgramData\Sophos\Web Intelligence\swi_ifslsp_64.dll' 45c.13f8: supHardenedWinVerifyImageByHandle: -> -22919 (\Device\HarddiskVolume2\ProgramData\Sophos\Web Intelligence\swi_ifslsp_64.dll)WinVerifyTrust 45c.13f8: Error (rc=0): 45c.13f8: supR3HardenedScreenImage/LdrLoadDll: rc=Unknown Status -22919 (0xffffa679) fImage=1 fProtect=0x0 fAccess=0x0 \Device\HarddiskVolume2\ProgramData\Sophos\Web Intelligence\swi_ifslsp_64.dll: WinVerifyTrust failed with hrc=CERT_E_REVOCATION_FAILURE on '\Device\HarddiskVolume2\ProgramData\Sophos\Web Intelligence\swi_ifslsp_64.dll' 45c.13f8: supR3HardenedWinVerifyCacheInsert: \Device\HarddiskVolume2\ProgramData\Sophos\Web Intelligence\swi_ifslsp_64.dll 45c.13f8: Error (rc=0): 45c.13f8: supR3HardenedMonitor_LdrLoadDll: rejecting 'C:\ProgramData\Sophos\Web Intelligence\swi_ifslsp_64.dll': rcNt=0xc0000190 }}} In addition, the computer I use has no general internet access (only some white-listed pages).
