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
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?
