3com 3300 Vlans and cisco 2600

I have a problem i currently have a 3com 3300 switch with all my
computers directly conected to it however i want to up grade
considering i just got a cisco c 2600 and i want to set it up as
router on a stick with multiple vlans (one for internet/web servers
and one for the local vlan) i have got the switch setup i think heres
that configuration basicaly:

hostname cisco

interface FastEthernet0/0
no ip address
no shutdown

interface FastEthernet0/0.1
encapsulation dot1Q 1 native
ip address 172.16.1.1 255.255.255.0
no shutdown

interface FastEthernet0/0.10
encapsulation dot1Q 10
ip address 172.16.10.1 255.255.255.0
no shutdown

interface FastEthernet0/0.1
encapsulation dot1Q 20
ip address 172.16.20.1 255.255.255.0
no shutdown

interface FastEthernet0/0
no shutdown

i have set up the 2 additional vlans in the 3com switch set up the
trunk port in features\trunk on port 1 both vlans are using 802.1q
config and so is the trunk but i am having problems pinging from a
computer attached to a port assigned to vlan 20 or either the switch
or the router
