What happens to VLANs 30 and 40 I can not do to communicate between them.

I enabled ip routing but I can not have communication from vlan 30 to vlan 40, 6224 I'm trying to L3 and a Power Connect 3424, from the switch and Laptop I try to ping an ip from vlan 40 in this case the you configure the router as the ip address of vlan 40. (172.16.40.1) timeout for this request. To test the communication between a WRT54G and configure VLANs in the vlan dhcp 30 once I get the ip of the vlan 30 trying to get communication with the vlan 40 but not function.

below are the two configurations one of the 6224 and 3424 another

Help me I'm new to this technology .. Thanks !!!!!
