Hi Roy - 

By any chance, did you also add 1.2.3.90 to "outside" at this time?

If so, SunScreen will still think that it belongs there, and
is likely dropping the traffic  as being spoofed. SunScreen 3.1 
determines that a packet is "spoofed" if it arrives on one interface,
but according to your interface address groups, it belongs to
another interface.  (you get spoof protection, btw, by accurately
configuring address groups associated to your interfaces, which
is required in Stealth mode to ensure that packets are sent out
the right interface).

>Does anyone have any idea as to what is wrong?

I would guess that spoof detection is getting you.  

To further debug this, turn on logging on your interfaces, then
examine your logs.  It will give the reason for dropping the
packet as either "Deny or no pass rule" (errorcode 256) or 
"Invalid source address "(errorcode 272)

hope that helps
