tnsping timing out when trying to connect

without issues. I have no trouble seeing the database instance on the server. But when I try to connect with the laptop, tnsping times out. I have no problem pinging the server from the client.

Here is the lsnrctl stat output on the server:

I am using a Netgear router WGT624 v3. The same client has no issue making a VPN connection to the outside world (true for server too).
