Done, and it looks like it is working the same as it was.

Fairly, I just don't know what component of it is having the problem.  The linux
server was just installed to take the place of a NT server running 'NetShare'.

I just found with ifconfig that my ppp link is reporting frame errors.

I also am looking for where to set 'TCP Sliding window'  I don't know if this
could be worth pursuing.

All of the machines behind the masq server have the problem.  As I said the email
worked before, although the path is now different (configured as dirrect connect,
where it was configured as some sort of proxy).  Also since this is intermittent
I was assuming it had to do with packets getting funneled in different order
through the masq.  (I don't have a clue)

Finially while going over HOWTO/*/IP-MASQ* files, I seen that I should have mtu
and mru > 1500, so I just changed that back.
