I am using VPN at home trying to connect oracle database at company. I do not have problem connect to our development database, but our production database is at another location, and there is a firewall and a switch between us. I can PING the machine with the IP address, but when I use TNSPING, even though it points to the right IP address, I always got the error that "operation times out " no matter how much I increase the CONNECT_TIMEOUT parameters in listener.ora, I am sure it is not that CONNECT_TIMEOUT in listener.ora is big enough.

Could somebody give me some hint how to fix this problem?
