Proxmox Vlan tagging issue.

[asingh]

Hi,

I upgraded from 1.9 to 2.x and problem is proxmox is only accessible from vlan1

proxmox on vlan4 (vmbr0 10.10.40.0) and Containers on vlan5 (vmbr5 10.10.50.0) but when I am in vlan3(10.10.30.0) I am not able to connect to vlan4(gui) or vlan5 but I can access vlan4 and vlan5 when I am in vlan1(10.10.10.0).

What I am missing? this setting was working fine in 1.9

Any help is appreciated.

Thanks

Hi,
sounds like an routing problem. Look with traceroute, and tcpdump to find the issue - and for help give us more informations!

If it worked in 1.X, it is maybe related to new settings in /etc/sysctl.d/pve.conf
