bitcoin client for mac won't connect, need help please

[stonehoo]

Here is the thing:
I have a desktop computer which is running windows 7 and an iMac.
Both installed with bitcoin clients.
It runs perfectly on windows all the time, I have 8 connections and 128343 blocks and growing regularly.
But the clients on Mac has no connections since this morning, and i reinstalled it, still has no connections, no blocks either.
I found this thread from google: http://forum.bitcoin.org/index.php?topic=10099.0
I ran the command, it came up with 1 connection, but blocks still no growing.
The two computers are running behind the same router, one is working fine, but the other is not working at all.
Can anyone out there help me?
thank you in advance.

all i worked it out.
I added forwarding rule on my router setting page which forwarded my mac's ip to 8333 port.
Now i have only 1 connections, but the block just started to grow.
