Hi All,

I'm pretty new to proxmox having previosuly used vmware and to a lesser extent xcp-ng. I have a fair bit of experience with debian, ubuntu and centos but this is my first time configuring a VLAN in linux I have an HP DL360 G8 server with an 560 SFP+ 10GB dual fibre card.

On the two 10 G interfaces was has both tagged and untagged traffic and the other is just tagged (the netwrok is too established and with too much hardware for me to easily change the untagged to tagged at this point).

I can talk ping my host on all interfaces but guest VMS can only ping the host and nothing else. As per another post on this forum I've reduced the number of vlan IDs after making my interfaces vlan aware but still no joy, any help that can be offered wopuld be much appreciated My interfaces file is below:

network interface settings; autogenerated
# Please do NOT modify this file directly, unless you know what
# you're doing.
#
# If you want to manage parts of the network configuration manually,
# please utilize the 'source' or 'source-directory' directives to do
# so.
# PVE will preserve these directives, but will NOT read its network
# configuration from sourced files, so do not attempt to move any of
# the PVE managed interfaces into external files!
