Trying to access my 851w from outside my lan, but can access inside fine

Question

Hi,
I purchased a 851w to use as my home router and to learn more about the cisco IOS. I have been spending some time studying for CCENT/CCNA and so far I have enjoyed learning as I go. However, I am having problems accessing this router from a remote location via ssh. I can access it just fine from my lan, but not outside it from another location. Currently, I am not using this router for internet access or anything else other than learning about the IOS, and it is connected to a basic dlink wireless router dir-615. I have port forwarding setup on the dlink that any traffic coming in on port 22 is directed to the 851w at 192.168.0.150. I also have the 851w connected with a crossover cable to a switch that is connected to the dlink router.
Like I said, I can connect just fine from my lan, but can't connect from outside. I have tried a few different things but nothing works. I also use Teraterm to connect, but have tried Putty too. I also use ddns to access it, but I have also tried the wan ip address of the dlink with no luck.
Could someone please take a look at my very basic running config and explain what I might need to do different?
Thanks in advance.
Sean

Hi and thanks a bunch for your quick response.
No, I can't ping anything other than my main router which I have setup as the gateway so why is that? For example,
ip default-gateway 192.168.0.1
Wouldn't it automatically send anything it doesn't know about to the 192.168.0.0/24 router?
I have one of the switch ports, Fast Ethernet 0, connected to another switch connected to the dlink router. I have tried different ports but it didn't change anything. I don't have anything connected to the wan port of the 851w. I was trying to simulate remote access of a switch on an internal network. My next step would be to make the 851w my default router and then try to access it from the outside, but I wanted to succeed this way first.

Interface IP-Address OK? Method Status Protocol
Dot11Radio0 unassigned YES unset administratively down down
FastEthernet0 unassigned YES unset up up
FastEthernet1 unassigned YES unset down down
FastEthernet2 unassigned YES unset down down
FastEthernet3 unassigned YES unset up down
FastEthernet4 unassigned YES unset administratively down down
Vlan1 192.168.0.150 YES manual up up
Yes, my internal pc is on the 192.168.0.0/24 subnet.
