    Does Router3 have a route back to 10.0.2.2, which is the source IP?

    Hi,

    Through ospf router3 must have learned about 10.0.2.2 

     

    I  executed ping from  FW cli , did not use any source ip address 

     

    from firewall local traffic log , I can see source is 10.0.2.2 

    Thanks

    That's the first thing I would check for any routing issues. Because that's the most common problem: route is not there.Then if all routes are there at all hops, it's time to sniff traffic at vdom2 "diag sniffer packet any 'host 10.0.2.2' 4" to see it's actually going out and a return comes back in.

    Since you never mentioned about a pair of policies at vdom2, I'm assuming they're there to pass traffic from/to the vdom-link to/from the interface toward router3.
