Hi, We have build Ovirt-engine self hosted. We have created 2 vlans 1 services and 1 student. This works good. Services vlan 192.168.60.0/24 gateway ip 192.168.60.1 on this card Student vlan 192.168.10.0/24 gateway ip 192.168.10.1 on this network card Everything seems to be oke, but the probem is on the vlan. On the node 192.168.60.3, there is no internet connection when we do yum update -y But there is no internet connection on the host. I cant do yum update -y or do anything else.

But only traffic from the insidehost to outside is not working. Thanks
