To do this, we need to add a custom route to the server, we need to add the network and netmask addresses, to test and see if it works:
route add -net 10.5.0.0 netmask 255.255.255.0 dev vmbr0
if it works, add the following to your /etc/network/interfaces file
iface vmbr0 inet static
…
bridge_fd 0
up route add -net 10.5.0.0 netmask 255.255.255.0 dev vmbr0
down route del -net 10.5.0.0 netmask 255.255.255.0 dev vmbr0
…
did not work? Remove route with:
route del -net 10.5.0.0 netmask 255.255.255.0 dev vmbr0
