I have created a virtual network bridge in open nebula with sunstone gui. The status is ready and I am using it on my vm. But why can’t the VM ping the physical network and not even the gateway and opennebula server? Is there any configuration I’m missing? root@malifax:~# onevnet show 18 VIRTUAL NETWORK 18 INFORMATION ID : 18 NAME : malifax net USER : oneadmin GROUP : oneadmin LOCK : None CLUSTERS : 0 BRIDGE : onebr18 STATE : READY VN\_MAD : bridge PHYSICAL DEVICE : enx00e04c360425 AUTOMATIC VLAN ID : NO AUTOMATIC OUTER VLAN ID : NO USED LEASES : 1 PERMISSIONS OWNER : um- GROUP : um- OTHER : um- VIRTUAL NETWORK TEMPLATE BRIDGE=“onebr18” BRIDGE\_TYPE=“linux” OUTER\_VLAN\_ID=“” PHYDEV=“enx00e04c360425” SECURITY\_GROUPS=“0” VLAN\_ID=“” VN\_MAD=“bridge” ADDRESS RANGE POOL AR 0 SIZE : 10 LEASES : 1 RANGE FIRST LAST MAC 02:00:ac:15:03:ee 02:00:ac:15:03:f7 IP 172.21.3.238 172.21.3.247 LEASES AR OWNER MAC IP PORT\_FORWARD IP6 0 V:32 02:00:ac:15:03:ee 172.21.3.238 - - VIRTUAL ROUTERS 52 VIRTUAL MACHINES UPDATED : 32 OUTDATED : ERROR : 8: onebr18: \ mtu 1500 qdisc noqueue state UP group default qlen 1000 link/ether 2a:29:49:bf:79:4f brd ff:ff:ff:ff:ff:ff inet6 fe80::2829:49ff:febf:794f/64 scope link valid\_lft forever preferred\_lft forever 9: one-32-0: \ mtu 1500 qdisc noqueue master onebr18 state UNKNOWN group default qlen 1000 link/ether fe:00:ac:15:03:ee brd ff:ff:ff:ff:ff:ff inet6 fe80::fc00:acff:fe15:3ee/64 scope link valid\_lft forever preferred\_lft forever 11: enx00e04c360425: \ mtu 1500 qdisc fq\_codel state UP group default qlen 1000 link/ether 00:e0:4c:36:04:25 brd ff:ff:ff:ff:ff:ff inet 172.21.3.237/24 brd 172.21.3.255 scope global noprefixroute enx00e04c360425 valid\_lft forever preferred\_lft forever inet6 fe80::3941:5540:652b:eb16/64 scope link noprefixroute valid\_lft forever preferred\_lft forever Can someone help me? ---

Hello @desi , Welcome to the Forum! It looks like your problem is very similar to this: > [@Bridge network not communicating to internet](https://forum.opennebula.io/t/bridge-network-not-communicating-to-internet/4494/2): > > Hi, In order to get your bridge working you need to attach br0 to your physical NIC so u need to check your bridge config instead opennebula. Another way to perform this action without attaching the phys.NIC is to make rules into your firewall redirecting the packets (see masquerade option if u are under gnu/linux). Cheers. (it’s on an old version, but should work the same way). Also, please check our documentation: [Virtual Networks — OpenNebula 6.10.2 documentation](https://docs.opennebula.io/6.10/management_and_operations/network_management/manage_vnets.html) If you still cannot make it work, let us know.
