Guest DHCP issue
Hello
I have recently added 2 new hosts to our cluster, but ran into an issue where guests do not receive a DHCP lease from the virtual router.
If I set the interface as static I can ping the router and all networking is fine. I'm sure must have missed a configuration step.
Any ideas?
CS version 4.11.0.0
libvirtd (libvirt) 1.3.1
Ubuntu 16.04
bridge-utils, 1.5
Thanks
Adam

Yes, check the firewall thing - it can cause many different issues if not
correctly configured... I have recently had some fun because of iptables...

Its related to UFW, if I disable that on the host it works, but all the rules look the same between hosts?
Thanks
