I can reach the destination host via the lxc, but if i'm sending ping packets with more than 1468 bytes, it runs in a timeout. So the overall packet size, which is working, is 1496. With lxc disabled but vlans enabled, it works fine. Also over the network bridge.

Did you try with the lxc.network.type=vlan ?
