The Problem: I cannot setup a connection between my Oracle client and the Oracle Server. I've had a friend who is an Oracle DBA look at my setup and the best he can come up with after a few hrs of tinkering with my network is that it's a firewall issue.
The facts:
[LIST=1]
- Astaro 6.304
- The 2 machines in question have static IPs. There's no NAT needed.
- Both client and server are Windows XP sp 2
- I cannot port ping any machines on my network on port 1521, which is the port Oracle uses for connections, by default. I get "machine actively refused" for any such port pings. I have tested more than just the 2 machines in question. No machines respond on port 1521.
- When trying a port ping, nothing shows in the packet filter logs as dropped. Actually nothing shows in the packet filter logs at all between these machines except for NetBui requests on port 137, which now I've also allowed, just in case.
- Windows Firewall is disabled on all internal Windows machines, or set to not monitor because of a self-monitored firewall solution like Astaro. [:)]
- At the top of my packet filter list are the following rules. I know this is inefficient, but I was trying anything and everything to get this to work.[LIST=1]
- internal (nwk) -> Oracle listener (port 1521, TCP) ->internal (nwk) -> allow
- internal (nwk) -> any -> internal (brdcast) -> allow
- internal (nwk) -> Oracle_SQL_NET -> internal (nwk) -> allow
- internal (nwk) -> Oracle_SQL_NET_v1 -> internal (nwk) -> allow
- internal (nwk) -> Oracle_SQL_NET_v2 -> internal (nwk) -> allow
- internal (nwk) -> any -> internal (nwk) -> allow
Thanks,
