The file created to connect the veth to the bridge in needs additional lines to deal with networks using differing MTUs. On a jumbo-frame network, the guests connected through the gateway will be unable to receive large packets without adding in:

    pre-up ip link set veth-br0 mtu 9000
    pre-up ip link set veth-br-ex mtu 9000
    pre-up ip link set br0 mtu 9000
