   @rafaelweingartner  We faced the same issue before.
   it is fixed by adding some rules in ip route tables.
   
   ```
   $ ip route show table Table_eth1
   throw 10.10.1.0/24  proto static
   throw 10.10.2.0/24  proto static
   ```
   eth1 is public interface
   10.10.1.0/24 and 10.10.2.0/24 are cidr of vpc tiers.
   
   The idea came from the code before 4.7 (systemvm refactoring)
   https://github.com/apache/cloudstack/blob/4.5/systemvm/patches/debian/config/opt/cloud/bin/ipassoc.sh
