[SOLVED] pve5.2-1 and windows network problem

[igonshi]

Hello everyone.

I have pve5.2-1 installed. Set up debian and centos as qemu guests. Have vmbr0 (Linux bridge) with single physical slave (eno4).

When trying to use windows server 2012r2 as qemu guest, I have a problem: can't ping my LAN gateway. This problem is only at windows vm(id-104). Found out (used tcpdump), that arp-replies from gateway are lost in interface of vm (tap104i0), while at vmbr0 I see that replies.

Spoiler: brctl show

root@hv01:~# brctl show
bridge name     bridge id               STP enabled     interfaces

                                                        tap101i0
                                                        tap102i0
                                                        tap104i0
vmbr0v110               8000.6c3be5bd8bfb       no              eno4.110
                                                        tap103i0
vmbr0v30                8000.6c3be5bd8bfb       no              eno4.30
                                                        tap100i0

Had anyone same issue?

UPD: Seems like I can't get arp replies from random hosts (not only gateway). Heh.
