seems that You created the br interface manually?

Don´t do that. Virtualizor will do that automatically.

At the node, change ifcfg-enp0s31f6 to this:

Code
DEVICE=enp0s31f6
ONBOOT=yes
BOOTPROTO=none
IPADDR=88.X.X.115
GATEWAY=88.X.X.65
NETMASK=255.255.255.192
DEFROUTE=yes

IPV6INIT=yes
IPV6ADDR=2a01:4f8:10b:197::2/64
IPV6_DEFAULTGW=fe80::1
IPV6_DEFROUTE=yes
IPV6_DEFAULTDEV=enp0s31f6



Then delete the  ifcfg-viifbr0 and route-viifbr0 files from the network-scripts directory.

Reboot.

Virtualizor will create the necessary interfaces / routes for you, but you may need to delete the IP pool and add it again. (Not sure about this)

Make also sure, Virtualizor knows about your network interface, specially if your node is a slave, you will need to set the interface in Configuration. If not set, virtualizor assumes it is eth0.

Hi,


If you are using only NAT ip pools then no need to create/start anymore bridges for now.
Regarding network for vps, can you show output of brctl show and ifconfig from server ?

Is that vps able to ping gateway from vnc ?

hmm, there is not much more you could do.

If you ping any other IP except the gateway (the first one in the subnet) and you get the output you provided means, they are routed correctly to the node. from there they stuck.

You should open a support ticket for that to have Virtualizor support have a deeper look insight.
