Powerconnect 8024F routing issue

Hi all,

Currently in the process of setting up routing and DHCP in order to use the switch as a default gateway instead of the router since the router is on a heavy load.

The topology is the following ROUTER - Dell Switch - Other switches 

Currently, the problem is the following: if a client from VLAN 20(10.1.20.0/24) connects he won't be able to access the internet without an additional default route being set (0.0.0.0 0.0.0.0 10.1.20.1). 10.1.20.1 is the router's IP address.

My question is shouldn't the switch use the default route that is already in place?

Here is my entire config:

console(config)#show running-config
