Since upgrading from srss_3.1 to srss_4.0, I've noticed something
peculiar with my Sun Ray at home, which is behind a NAT router.  I get
a timeout when logging in or logging out, but not when connecting or
disconnecting with my smart card.  The same timeout happens when
starting the Sun Ray connector.  During a timeout, the Sun Ray goes
dead for a few minutes, until it reboots.  I get a locked screen when
that happens.  Sun Rays at the office don't exhibit this behavior.

One thing that I notice is that the firmware on this Sun Ray is still
3.1_32,REV=2005.08.24.08.55, whereas all the others at work have
firmware 4.0_48_2007.08.01.15.48.  Is this the cause of the problem?
If I set up a firmware server in the local DHCP configuration, will
it download the new firmware?

Is perhaps something blocked by the NAT router?  I'm using ipfilter in
Solaris 10 8/07 for this.  Snoop tells me that the normal traffic is
mostly UDP, but during the timeout the UDP traffic seems to stop.  At
that point, the Sun Ray server seems to stop responding to UDP,
issuing ICMP Destination unreachable responses.  TCP does start up in
both directions, but traffic is still mostly gone.  After some time,
the Sun Ray times out and resets.  That's when normal traffic resumes.
What's going on here?
