Unable to communicate between VLANs on SG300-10

Level 1

Please take a look at my rough drawing of how I would like my network to work:

                        SG300-10
       __________________________________________
       | 1 | 2 | 3 | 4 | 5 | 6 | 7 | 8 | 9 | 10 |
       |_|___|__________________________________|
         |   |_________________________________
         |_________________                   |
__________________  _______|_________  _______|_________
|-----VLAN 1-----|  |----VLAN 10----|  |----VLAN 20----|
|   Management   |  | 192.168.10.1  |  | 192.168.20.1  |
| 192.168.1.250  |  |               |  |               |
|________________|  |Internet Router|  |   Devices:    |
                    | 192.168.10.2  |  | Physical Box  |
                    |_______________|  | 192.168.20.2  |
                                       | Server 2008R2 |
                                       |DNS,DHCP,AD DC |
                                       |               |
                                       |Physical Boxes |
                                       | 192.168.20.x  |
                                       |W7 Workstations|
                                       |_______________|

I have set static IP addresses on the Server 2008R2 host and Internet Router.  I set up my VLANs, and I set each VLAN IP (as shown above), I set a 0.0.0.0 route to the Internet Router as well as x.x.x.0 routes for each VLAN IP range, and I set the gateway on all hosts on VLAN 20 to be 192.168.20.1. 

I am unable to get Internet access, ping the router or access the switch management web page from any host on VLAN 20 unless I manually set the IP on the host on VLAN 20 to the same IP range as the device I'm trying to access. As such:

If I manually set the host IP to 192.168.1.50, I can access the switch management, but then cannot RDP into or ping any of the hosts on VLAN 20 or ping the Internet Router on VLAN 10.

If I manually set the host IP to 192.168.10.50, I can ping the Internet Router but cannot RDP into or ping any device on VLAN 20, nor can I access the Switch Management page.

If I allow DHCP to set the IP to 192.168.20.5, I can RDP into and ping all devices on VLAN 20, but I cannot ping any devices on VLAN 10 or access the Switch Management on VLAN 1.

I know I'm missing something simple, and I've been working on this for about 30 hours now but cannot seem to get this to work. Could anyone possibly help?  Thanks in advance.
