    We have got a NAT IP address and a open port 1521, But having trouble
    in connecting the database.
    Not working (Timeout Error) - ORA: 12535 - TNS: operation timed out

    Please suggest for this.

    Is NAT working ... do you see the natted packets come out the other side of
    the firewall / router? Are your access rules working ... does anything come
    out the other side? Is the servers port listening ... does it send RST's?
    A lot can be learned by sniffing the network and investigating system logs.

    What's actually between the client and server?

    Oracle used to require a special handling with NAT, i.e the device doing the
    NAT had to know how to NAT the packets because information about the
    connection was embedded in the protocol. Did a quick Google search and
    found the following link which should be helpful.
