We have a few linux webservers with oracle client and a handful of oracle database servers running on linux and windows, the webservers and the database servers are on seperate networks. Currently we have pix firewalls between them. I am trying to setup an IPtables firewall on a linux box but am having trouble as the listener communication happens over a random port once the inital connection is made over port 1521. Has anyone had any experience of this? has anyone seen any docs around on this? any help would be gratefully received.

thanks,

dan...

hmm..

In a nutshell, I'm stuffed, we are currently using nokia / cisco firewalls and wanted to move to linux based firewalls so we could provide gigE all the way from our webservers to databases.

The only "workaround" I can find is to set the SHARED_SOURCE_PORT option so that all communication happens via 1521/tcp, does anyone have any experience of this?

thanks,

dan.
