What you should do is to take the info on exactly which ports you are
using - 1521 or 1526 or other non-standard ports and have the firewall
administrator temporarily open those ports for incoming and outgoing
traffic.

One important issue to consider is that this type of connection(from a
security perspective) should in general NEVER be allowed.

Hi all,
I'm trying to connect to an outside Oracle 7.3.2.3.0 database from a
client behind my firewall (MS Proxy 1.0) but I just can't get SQL*Net
to
work.

When testing the connection, I receive the following error message:
ORA-12545: Connect failed because target host or object does not exist

 I have also contacted Oracle for information about this problem, but
I
didn't really understood what exactly I can do about that, since I'm
not
really a network expert. They said something about a port problem when
the packets return from the db.

So does anybody have an idea what I can do or is it simply impossible?

thanks in advance,
Chris
