[ipxe-devel] Problem with accessing iPXE via UNDI

The most recent version of Syslinux supports a builtin TCP/IP stack
which is used to handle HTTP-based protocols.  This works well on
traditional PXE stacks, but it fails horribly on iPXE.  The reason seems
to be that iPXE, with its own builtin TCP stack, sends an RST in
response to any incoming TCP packet with a port number it doesn't
recognize, even though it has an NBP as an UNDI stack listener open.

I am wondering how best to resolve this.  There are a number of people
affected by this problem.
