William, the problem is now fixed - unintentionally and I still don't 
know  why all these happened;

Since you mentioned that there is a possibility that the firewall may 
have blocked the remote vnc client,
so I disabled the firewall  by Main menu->System settings->Security 
level, and then the remote vnc
client can connect  to vnc server at port 5811.

But since then, the remote vnc client can alway connect to vnc server 
with the port 5811 even I enable
the firewall again up to now.

So the fix is - Turn off the firewall and turn it back on again! I don't 
have a clue what happened.
