PLSQLDeveloper and Windows firewall

[jasbo]

I have an Oracle instance on one Windows machine. To get TNSPING to work from another computer I needed to add TNSLSNR.EXE to my exceptions list on my Windows Firewall. When I try to connect to this instance from my laptop with PLSDev I get ORA-12170 error. If I turn off the firewall I can connect and transact. I assume I have to do something to the firewall setup to get this to work. Can you tell me what I have to do?

get kerio firewall. much better than MS one and you will see what you need to add to the rules.

You probably need to add oracle.exe as well. I'm not 100% sure though.
