Does OSPF work to the inside?

Can you remove the filter from the outside completely and see if it pass's
packets? ( obviously not on the internet !)

Did you use the same area under the interface as you defined in the ip
routing section?

What do you mean by #6 ? By default ospf is filtered by the "public default"
filter, so you would need to add it to the filter. I didn't understand if
you added it, or if you thought it was already added. It should appear on
the left side of the filters list for it to be active. 

Other than those questions, it sounds like it should work. I run OSPF on my
concentrators at work, and it was pretty simple to setup. Biggest issue I
had was advertising my remote ospf networks into OSPF. Took me several hours
before the check mark for ASBR jumped out at me!

    I have done the following steps .

  1. Set OSPF Router ID
  2. Enable OSPF
  3. Defined the area
  4. Enable ospf on the outside interface
  5. Assigned Public defacult filter to Ouside Interface
  6. Checked the filters for OSPF in / OSPF out.

   But still VPN is not sending any packets to the outside.. I did a debug
on the router I am not receiving any packet on the router from VPN

If any body has any clue please help me

What all have you done to enable it?

You need to enable ospf and provide its parameters under the interface
itself, and you also need to to enable OSPF under ip routing as well.

Does it work to the inside?
