i have a basic network bridge configured as below
pve host
Code:
auto lo
iface lo inet loopback

iface enp62s0np0 inet manual

auto vmbr0
iface vmbr0 inet static
        address 10.10.16.105/24
        gateway 10.10.16.1
        bridge-ports enp62s0np0
        bridge-stp off
        bridge-fd 0

on vm,

however vm cannot reach the gateway

Hey,

do you have the firewall configured?
 
Can you check on the gateway, if incoming traffic of vm is visible there?
I don't have privilege to check that on gateway side..


meanwhile i did some additional tests
1. arp table

Is there a firewall on the gateway or port security on switch is active? Because it seems not to be a PVE problem but on network path to the gateway or gateway itself.
