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.) /Hans |

It should make all connections going thru the listener port socket (1521 in your case). Ymmv! -- Regards, Frank van Bortel |
