ipxe -> symantec pxe chain

[wdriever]

Hallo all,

Could someone help me with the following?:

We boot our clients using ipxe, users get a menu to boot from.
One of the options is Altiris(symantec).

We chainload using the following command:
chain tftp://192.168.200.28/BSTrap/x86pc/BStrap.0, this works in BIOS.

For UEFI we use:
chain tftp://192.168.200.28/BTrap/X64/BStrap.efi

This give us the error:
Proxy offer not received Failed to initialize application
PXE-E16: No offer received.

If i leave out ipxe and directly boot Symantec via pxe in UEFI, it works after setting option 60 PXEClient.

Using wireshark without ipxe i see that symantec does a ProxyDHCP, some this does not work from ipxe.

Could someone help me with this i have tried a lot of things but i am not able to resolve it?

Thank you
Wietse
