Hi,
I have only experience with Oracle Net Services and Oracle 9i R.2. I'm now confronted with 2 Oracle8i Release 8.1.7.2.0 servers.
I'have read this 3 sentences:
"SQL*Net traffic should not be allowed to pass through firewalls unless absolutely necessary. Firewall filters should be designed to only allow SQL*Net traffic from known application and web servers. Few applications require direct SQL*Net to a database from the Internet."
1. I would like to know what is SQL*Net versus Oracle Net Services? Is it he same but for an Oracle 8i version? Are they playing the same role?
2. With Oracle Net Services and in a Client-Server application or Java Application Client (web server) connections: Oracle Net is always installed on both the Oracle database server and the Application side! So I'm a bit confused with: "Few applications require direct SQL*Net to a database from the Internet."? I feel I'm quite mixing now...
3. What should I interpret with these 3 sentences and SQL*Net? Practically what does it mean what should I actually do in my server configuration to apply this about SQL*Net?
Many thanks for your help!
Best regards,
Patrick Tahiri.

1) SQL*Net versus Oracle Net Services
Net Services it's a brand new name for the 'old' SQL*Net software.
we are talking the same software.
2)Yes, you will have to install SQL*net (or Net Services) both sides: database server and Application server. Because JAVA programs will use SQL*Net from the application server to access the database server.
I believe question 3) will get clear to You after reading answer 1 and 2.
Best luck.
