Syslinux - Jul 2015 - [PATCH] Updated udp.c to use real client ip and subnetmask values if on local subnet

Gene,

I am very sorry. I did try the patch you suggested and had the same issue. 
Then, I grabbed the latest patch on Patrick's git repo. That's the
commit
that I listed. It was posted two days ago.

I just noticed this on Patrick's repo: This branch is 6 commits ahead, 2 
commits behind geneC:master

1) I don't see this commit ID.

2) Did you try commit ID 5186539 without this patch?  If so, what did
you observe?  I believe I asked you to try a more current commit but
never heard a response.

That explains that.

What about the observed symptoms?  Have you performed an inline packet
capture or capture of a packet mirror?  Looks like I should try to
improve the instructions at
http://www.syslinux.org/wiki/index.php/Debugging#PXE-Capture-Mirror to
provide examples for Cisco and HP and an inline example with Linux
bridging.

Reading back, you stated "Strange thing is that the struct shows
0xc78cef71 for StationAddress and 0xc78cef75 for subnetmask when
usedefaultaddress is set to true.  Since my subnet is 10.39.31.xx, I
am completely baffled as to how the default values were set but I will
figure it out. I just need to do some additional digging."  Did you
obtain this based on extra Print() statements?  They look to be
adjacent memory addresses and not the contents of those addresses.

Have you tested this with accessing both subnet-local and
subnet-remote servers (ie, TFTP servers)?

Jeff, there's specific code that creates specific responses that if
you had mentioned what you saw, I'd expect we could have seen
something sooner.
