It's a reset of the connection (termination). If I read that string properly,
it looks the 206 address is resetting the connection, which is what I think
Greg (right person?) was meaning when he said it looks like a client side issue.

Here is a dump off the ISA server just taken now using Ethereal. This
time I just used the access rule I created for PPTP and L2PT which gave me the
619 error machine. I looked it up and several sites say that you need to have
port 1723 option and protocol #47 GRE as well. I don't see any GRE in ISA's
protocol list so I am not sure if it's open by default or not.
