3925e and SM-ES3G-16-P cant ping anything get past router from switchport

[khatiblou]

I'm at a loss, either this will be a something simple I overlooked or something bizarre.

Starting with the switch

- port gi 0/18 is configured with 10.10.100.2/30 as per most documents

- port gi 0/17 I have configured as a trunk port and tried just leaving it Default.

- port gi 0/2 is configured as an access port vlan 102

- I have created vlan 102 with an ip address.
- I have set the last resort route to point to 10.10.100.1/30 which is on the routers

At the router

- Has Gi0/0 connected to the internet

- from the router I can ping 4.2.2.2

- I have configured gi 2/0 (verified with cdp that this is the port created upon card insertion) With the ip of 10.10.100.1/30

- I have configured a  sub-interface gi 2/0.102 and used encap dot1q 102

- I have created a route for vlan 102 that points to 10.10.100.2/30

The results are with a PC with a valid IP from the vlan 102 subnet I can ping the the routers gi0/0 interface and can get no further. I can not ping 4.2.2.2.

Any help would be appreciated.

Is NAT configured on the router?

The IP I'm using on vlan 102 is a public address, NAT will be the next hurdle for some of the private IPs that will go on other ports/vlans on the SM switch card.

Does the router have a default route pointing to the service provider's IP?

Yes it does, I can ping 4.2.2.2 and 8.8.8.8 from the router but not from the switch card
