Cisco Routers :: Configuring SF300 For VLAN Routing?

getting a SF300 to properly route IP between 2 VLANs. I've watched the demo video and performed everything it showed, but I get the most bizarre half-way results. I haven't done anything on Cisco routers in about 15 years, so I'm a little rusty.
 
We have an office LAN with a cable modem/router for Internet access where the modem/router has IP address 192.168.1.1. We have the usual 24 bit prefix net mask. The SF 300 is connected to this network on port 1.
 
I have configured port 1 to VLAN 1, interface in Access mode, assigned a static IP address of 192.168.1.36, which is a free address on our office LAN. I have configured port 2 to VLAN 2, interface in Access mode, assigned  a static IP address of 192.168.3.1 I put a static route in the modem/router, pointing 192.168.3.0/24 to 192.168.1.36.
 
I have a PC on 192.168.3.10 attached to port 2.
 
The SF300 can ping 192.168.3.1, but not 192.168.3.10. 192.168.3.10 can ping 192.168.3.1. It can also ping 192.168.1.1, and can pull up an HTTP router admin page from 192.168.1.1. 192.168.3.1 can be pinged from anywhere on 192.168.1.x, but 192.168.3.10 cannot be pinged from 192.168.1.x. Finally, 192.168.3.10 cannot ping any other addresses on 192.168.1.x except 192.168.1.1, and cannot reach the Internet.
 
Here's my configuration:
