I have been having some trouble with Jumpstart and FTP.  On the jumpstart, the 
jumpstart starts and hangs.  If I change the mtu settings on the nic to 1496, 
it will start and run for a while and then hang.  Without changing the mtu 
settings on the NIC, I'm unable to ftp.  does anyone have any idea how to 
correct this issue?

Here's the release info:

Current network settings on the Jumpstart Server:

The jumpstart hangs on the client:

After changing the mtu settings to 1496, the jumpstart goes further but it 
still hangs.  Also, ftp doesn't work unless I change the mtu settings to 1496:
