Multiple NIC's and Vlan, Unable to PING to Gateway

[xateayam]

Hi folks,

I'm a newbie on proxmox envy. I'm using VE 6.2.-4.
Currently, I have 3 nic's.
eno1 attached on vmbr0 uses for management with 10.21.4.10/24, gateway 10.21.4.254
eno3 and eno4 attached on bond0
And, I configured vlan1, and vlan100.
vlan1 10.21.4.0/24
vlan100 100.100.100.0/24
vlan1 has configured on vmbr0 with 10.21.4.12/24
vlan100 has configured on vmbr100 100.100.100.254/24
The plan is, all VMs are going to be configured to 100.100.100.0/24
All these configuration has done.
All VMs able to be accessed each other and able to PING.
I have 2 VMs. One with 100.100.100.174 and 100.100.100.15
My VMs are able to PING to 10.21.4.10 (vmbr0), but all VMs unable to PING to 10.21.4.254 as gateway of vmbr0.
So, what should I do to make all VMs to be connected to the gateway 10.21.4.254?

Here is my /etc/network/interfaces :

root@pve1:~# cat /etc/network/interfaces

# 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!

Hi and welcome,

I'm using VE 6.2.-4.

please update to the current Proxmox-VE version [1]

You should never use VLAN 1 because this is not exactly defined what it is.
VLAN1 is also interpreted as no VLAN.

Also if your Switch does not connect VLAN1 and untagged it is not p[ossible that you reach 10.21.4.10.
Proxmox does no routing in default mode, so the connectivity has been done on the switch.
