Westell Wirespeed B90-220030-04 and Oracle Services

[Vern]

Hello All,

I have the above DSL modem on my network along with a variety of machines
and several different operating systems. One of the operating systems I have
is Novell 5.1 and on that server I am using the five user versions of Oracle
that ships with Novell. The Oracle version I am using is 8i. The server
bundle works great and I do all of my business on this platform.

I also have DSL, Novell (v5.0 and Oracle 8), running at home where I have
several databases that I rely upon heavily and it works great as well. My
dilemma is that I want to be able to access my work Oracle instance from
home. Incidentally, I have the identical Westell at home as I do at work.

I have opened up ports 1521-1526 with a base port of 1521 on the Westell at
work, (both udp and tcp), and managed to get a login prompt from sqlplus but
I'm never able to get logged in. It seems that Oracle is using a different
port each time I try to connect for communications. I could open up all
ports on my Westell but you know what that will do to my security.

Does anyone know what I need to do to have the ability to control this? Is
there special software I need to install to install on my Westell or is
there a way to instruct Oracle to use specific ports?

Thank you in advance for any help you may be able to provide,

Vern

Yes, Oracle port 1521 is used only for the initial connection and the
Listener will then inform your 'client process' and it's 'server process'
which port they should continue to use.

This is addressed by Oracle for some firewalls, and documented in the Oracle
Networking documentation (Which, IIRC is Net8 for Oracle8i) as well as
Metalink. Suggest you check Metalink for certification with Westell. (At
one time searching on 'firewall' in Metalink would provide sufficient info
but I have not looked for a while.)
