 I see something similar on a machine with a qfe (4 x hme) sbus card that
 I use as a NAT firewall/router.  Both internal and exteral networks are
 on the qfe card.  If "tcp4csum-rx" is enabled on the internal interface,
 FTP connections from the local LAN are not forwarded to 'ftp-proxy'.
 
 There was one remote machine I connected to that would drop the SSH
 connection with similar messages to those reported here, but it was
 the only one that exhibited the problem.
 
 Lately, I experienced one particular web site that starts to work then
 fails and, once failed, fails for all hosts on my internal LAN for a
 couple of days, including one running redmond-OS.  The webside works
 for hosts outside my LAN (via excruciatingly slow X11 forwarding over
 SSH).  I briefly disabled all tcp4csum for internal and external networks,
 but that didn't help.  I'll try again by rebooting the firewall so it
 comes up with those options disabled.
