Hi
Have you guys gotten this to work? I have a customer that this is not working as it should.
The customer have lots of remote offices running RAP's today, after plugging a PXE computer in an ethernetport on the RAP, the client do get an IP and such.
I have included the option 66 and 67 to the DHCP scope.
At this point, the PXE client is not working, TFTP server timeout.
Even tho we have plugged a windows computer into the same port with a tftp client on. Running a this client we are able to download the image.
The funny thing is that when adding an ip helper-addres to the vlan, the PXE client is working all of a sudden.
IP helper-address are forwarding a few UDP ports, so it might make sense that it wont forward broadcasts across L3 connections.
The ip helper-address is pointing towards the TFTP (SCCM) server and not to a external DHCP server.
The customer also have a 620 controller on a larger office, connected to the master via Internet. Local subnets/vlan's are routed thru the master-local IPsec tunnel. This works great for all other stuff, like AP's, RADIUS etc.
Adding the IP helper-address on the 620 controllers VLAN should do the same trick if i'm not mistaken.
But when we try to plug a computer doing PXE boot into a port on the 620, setting up a DHCP scope with the same options and also adding the ip helper-address, the bootp system will not work.
