Inter Vlan Cisco

Dear experts,

i am facing problems with inter vlan communication between vlans.
i am having layer 2 switch 3com 2952 with layer 3 capabilities.
recently i had brought a cisco router 1921 series.

i had created 2 vlans -  vlan 3 and vlans 4 in the switch.

one port is hybrid port which is connecting the giabiabit port0/1
 of cisco router 1921.
please see running config for my cisco router
