Question regarding guest LAN + host bridge network

[cmonty14]

Hi,
I have the following question regarding guest LAN and host bridge network:
Can I setup a guest LAN in network segment
10.68.88.0/21
if my host network configuration has default bridge
auto vmbr0
iface vmbr0 inet static
address 10.96.131.9
netmask 255.255.255.0
gateway 10.96.131.1
bridge_ports ens4
bridge_stp off
bridge_fd 0
?

If yes, how should I configure guest network (Default gateway, etc.)?

THX
