connecting through a router

[yogurtu]

Dear sirs:

I have installed Oracle 9i in a W2K server, and I can acces it from any workstation in the LAN (by installing Oracle Client).

I cannot understand why I am not able to connect from an "external" PC with the same Client and configuration.
This external PC is accesing from the Internet through the port number 1521 of the router, which is open and redirected to my Oracle server.

Is this a normal issue? Other databases (like SQL Server) are working fine on that server without doing anything else...

I would be very grateful if somebody can write a line with a comment.

you are saying that you are trying to connect to port 1521 via the internet? I dont think its going to work for you. you have to be logged in that network's domain in order to access the database. I suggest that you do your research on networking.

do you have firewall?????? that's probably why

It would be irresponsible not to have a firewall of some kind (perhaps included in the router?). Look here http://forums.dbasupport.com/forums/...threadid=38541 for a reference.
