Hi all. I have a Cat6509 with multiple VLANs set up. I have helper addresses on each VLAN pointing at the correct DHCP servers so all clients can and do get IP addresses automatically, but my IBM Blade server farm is not able to PXE boot. The management server the blades want to speak to is in a different subnet from the blade servers and is already in the helper address statement, but none of them chat to each other unless they are in same subnet! Any ideas?
