Connecting to oracle database instance running on VM(Guest Computer) from remote computer

I have oracle database instance up and running on vmware player on Redhat linux(Guest OS). This virtual machine is running on on windows 7 computer(Host OS). I am able to connect to the database instance running on vm using sql developer which is running on my windows7 computer.

But when I try to connect to this database instance from my mac os, sql developer running on mac os can not connect to this database instance.

but , I am able ping my windows7 ip address from my mac os,

I am able to telnet port 80 on my windows7 computer from mac computer.

But I am unable to telnet port 1521 from the mac os.

Could anybody help me to configure my macos and windows7 computers to connect to database instance which is running on vmware player.

Thanks in advance for any help

Check what network configuration you are using in your guest. You’d probably rather use bridged mode to get the guest on its own IP address.

Check the firewall on your guest isn’t blocking and the Oracle listener to make sure it’s bound to the IP address.
