PXE boot not traffic allowed across Enterprise
Hi,
I have inherited an administration role in which my machines are imaged in a lab with PXE boot enabled. The tech before me had set up the GHOST server to listen for PXE traffic (tftp- I think???). When a machine boots from the network adapter, it picks up on a menu the Ghost server provides. In the lab all is well.
Outside the lab I guess network admin is not allowing the traffic out. Is it tftp traffic that is being blocked. If their is a concern then what would be the best way to propose to the network admin we allow the ability to GHOST machines outside the lab, still keeping him happy that is.

Tftp traffic has to be allowed, but you also need to have broadcast traffic working. Broadcasts do not go across routers. I assume all of the computers are the same or similar hardware? This solution should be tested thoroughly, then put on a server on the network and then assigned to the client machines as needed. This is my recommendation.

Could something like this work... You allow tftp, then the broadcast packets for the PXE are 'packaged' inside a type of packet that is allowed? What about some kind of 'forwarding' being done across the router? Are their rules on the router that can be configured to accommodate?
I did some reading awhile ago about about bootp supported through forwarding the traffic?

Do you know if you are using a PXE or bootp configuration?

More info...
We are running a GHOST server, the client boots off a nic and getting an ip addr (bootp) and a net config file. They are prompted for credentials and a .bat file gives them a menu of 1-9 to choose from. They select, then get the appropriate image.
I was not there for the setup of the GHOST server and the config file (watch it and it looks like a network boot disk being run).
I would like to know how they did it... GHOST server running on Win 2003 server.
