Hello,
I got stuck with the following:
Two VLANs (1 and 12) are configured on a Proxmox server:
There are two OpenVZ containers in different VLANs. They use different bridge interfaces - vmbr0 and vmbr12:
Here is an output from inside the containers:
Container #100 works OK, while #106 is the issue. I can ping it from the proxmox host itself only. When I try to ping from somewhere else, I see arp requests on vmbr12 and no replies. tcpdump from inside the container keeps silence.
Any ideas what's wrong with it?
Thanks in advance!
