Connectivity Error through ISA 2006 firewall

Question

Hi all,
i have problem connecting to my main database for syncronization, when i try to connect my clinet machine to the server over the internet directly to my main server it works but when i try to connect trough the firewall it gives me TNS:operation timed out... even though i have 1521 & 1526 ports are open on my ISa 2006..
please suggest do i need further listenr configuration...
thanks in advance..

For 8i and a shared server architecture, such a configuration (init.ora) should work:
local_listener="(address=(PROTOCOL=tcp)(host=hostname)(port=1521))"
dispatchers="(address=(partial=true)(protocol=tcp) \
(host=hostname)(port=5000))(dispatchers=1)"
dispatchers="(address=(partial=true)(protocol=tcp) \
(host=hostname)(port=5100))(dispatchers=1)"
dispatchers="(address=(partial=true)(protocol=tcp) \
(host=hostname)(port=5200))(dispatchers=1)"
Listener's port is set to 1521 as usual, dispatchers are set to fix ports 5000,5100,5200 (port numbers as an example). These number have to opened by the firewall administrator.
