At home I have a Linux-server with Oracle 9i server installed.
I want to connect to this Oracle server from a client PC (Win 2000) through SQLNET.
When my client connects to the internet through a phone-line (modem) everythings works fine.
When my client (laptop) is hooked up to the network at work, the connection fails. I guess the firewall at work is preventing the client-server communicaton.
What does work:
- SSH using putty.
What does not work
- tnsping --> I get a timeout message. ORA 15535
- db-server setup is dedicated not MTS, so I guess there is no port-redirection.
Read a lot about port-forwarding, not sure if this is the key ! and if it is, how to make this work.
