Hello everyone,
Would a pve that's hosting machines on more than one vlan need to have a different default gateway configured on each vmbr subinterface?
the network is set up like this:
all network devices: firewall, switches, access points, etc.. go on the management network: 10.100.99.0/24 with the firewall's management vlan, tag 99, subinterface as their default gateway: 10.100.99.253
everything else goes on the default vlan and has the firewall's lan interface as a default gateway: 192.168.1.253/24
the pve hosts various services on the default vlan, mail, web, etc..
however i'd like to setup a management console vm that also has access to the management network.
on the vmbr0 i created two subinterfaces: vmbr0.1 and vmbr0.99
if i try to add the default gateway to the vmbr0.99 subinterface i get error 400:
Parameter verification failed. (400)
gateway: Default gateway already exists on interface 'vmbr0.1'.
I know that i can edit and manually add the firewall's vlan 99 subinterface
to the proxmox vmbr0.99 in the "/etc/network/interfaces" file.
Would having (or not) a default gateway on more than one interface create routing conflicts of any kind for the pve or its hosts?
Thanks for the dedicated time,
Have a good day

Code:
root@pve01:~# 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!
