Hi all

Current setup:
Vodafone VDSL
Sophos UTM 9.5 running on an Intel NUC
nic0 -> lan
usb\eth nic1 -> DrayTek Vigor130 (PPPoE pasthru)
UTM handles creds and vlan tag of 10
Modem has no real configuration apart from passthru ticked
Running sweet as no problems.

So I build an ESXi 6.5 with 2x nics (HP desktop)
built-in nic0 -> lan
TPlink 3648 nic1 -> Draytek
VMXNET3 drivers

I built a Sophos VM with same config, modem config untouched but the UTM wan nic1 never comes up.
UTM PPPoE error log bleats on about timeout waiting for PADO packet
Modem reports no response from server-end (or something to that effect)

Thought it might be esxi dicking over the vlan tag, so set vlan10 on the vmkernel, no change

Changed esx driver to that off e1000, no change

Swapped nics over, so onboard went to modem and tplink went to lan, no change

Dicked around with various modem settings, no change

Smacked head on wall, no change

Any idea's on what could be going wrong?

You are setting the WAN side to VLAN 10 and not the LAN right? I would have thought you would need to set the WAN side VLAN on the modem.

Yep WAN side of UTM set to VLAN 10. Modem is told to do nothing except passthru whatever UTM sends.

Current configs below.

UTM

Modem WAN

Modem PPPoE

So I guess ESXi must be messing it up somehow

have you set the pass through up correctly on the esx host?

Yep I transferred the exact same working UTM settings as show above, into the VM UTM on the esx host

have you created a separate v switch? using a separate nic on the vswitch? if not this could be your problem, also i used the E1000

this is how i had my vswitch configured on 5.5

and then the vm it self

ESX does that for you when you "add networking" so yeh separate nics on separate vswitches

I might muck around with the esx hardware passthrough and present tp-link nic straight to the UTM VM

See what that does...

Set the DV130 as MPoA like this, just tick the 'Enable Bridge mode' nothing else needed

With the DV130 if you leave the VLAN blank then it leaves it alone and passes it through
If you set it on the DV130, then the DV130 removes the VLAN tag on the way in.
Meaning that you don't have to worry about it on the LAN side
This is how I work it with my ERL3, I don't need to set up a VLAN for my ISP, but I do require a VLAN to connect (hope that makes sense)
Here is my VLAN setup

And my ERL3 settings not a VLAN to be seen

If pass the VLAN through DV130 then I need to setup a VLAN on the ERL3

Hope this helps

I did try that, setting the vlan10 on the modem, still no go. Who knows I could of naffed some setting up, but I don't think so.

Anyway I got it working (using original settings above) by using hardware passthru on the esx hosts and presented the wan nic directly to the UTM vm.

Happy days!
