Hi there,
ASG 8.102 virtualised (vSphere 4.1 Update 1)
Three interfaces
I need to bridge two VLANs - both VLANs are public internet facing:
VLAN1: the real interwebs
VLAN2: a myriad of KVM based VMs
It's not possible for me to route or NAT.
The VMs (CentOS 5.5) on VLAN2 need public internet DHCP lease as they are instantiated.
So I though - easy - bridged interface, packet filter rules on the bridge along with DHCP.
Well ... what happened is astounding - you can spin up the DHCP server - but as soon as the first VM requests a lease dhcpd is at 100% as literally thousands of DHCP responses are pumped out of the DHCP daemon.
The VMs (all 2 of them) do get a lease but the DHCP server goes mad issuing close to 225000 duplicate leases in 15 minutes and close to 10Mbps of broadcast.
Bug ... anyone else seen this ... or a I committing a cardinal sin of putting a DHCP server on a bridge?
Thanks!
James
