External network Cannot ping vm successfully

My environment is ubuntu 13.04 64bit server and openstack grizzly, single node with OpenVSwitch. Here is my config:

/etc/network/interfaces

# The loopback network interface
auto lo
iface lo inet loopback

auto eth0
iface eth0 inet static
        address 10.2.0.41
        netmask 255.255.255.0
        gateway 10.2.0.1

# The primary network interface
auto eth1
iface eth1 inet manual
        up ifconfig $IFACE 0.0.0.0 up
        down ifconfig $IFACE down

auto br-ex
iface br-ex inet static
        address 10.2.0.36
        netmask 255.255.255.0
        network 10.2.0.0
        broadcast 10.2.0.255
        gateway 10.2.0.1
        # dns-* options are implemented by the resolvconf package, if installed
        dns-nameservers 61.147.37.1

tenant_network_type = gre
tunnel_id_ranges = 1:1000

local_ip = 10.2.0.41
enable_tunneling = True

#Firewall driver for realizing quantum security group function
[SECURITYGROUP]
firewall_driver = quantum.agent.linux.iptables_firewall.OVSHybridIptablesFirewallDriver

I have two vms, 10.2.0.51 and 10.2.0.52 of floatingip, 192.168.100.2 and 192.168.100.3 of internal ip. In vm, I can ping both floatingip and internal ip succcessfully, but the vm cannot reach external network and either external network. I cannot ping successfully 10.2.0.50 that is the router gateway.
