Error line 68 in DBMS_DEBUG_JDWP when trying to debug from behind firewall

Question

Hello!
I am using sqldeveloper on a windows client, connecting to an Oracle 10.1.0.4 database on AIX 5.3 behind our internal firewall. No sweat, I have an sql*net "hole" through the firewall to the database listener.
But when trying to debug a PL/SQL procedure, the debugging session cannot start but gets the following errors:
ORA-30683: failure establishing connection to debugger
ORA-12535: The requested operation could not be completed within the time out period.
The cause is readily seen in one of sqldeveloper's own windows, namely that the procedure call
CALL DBMS_DEBUG_JDWP.CONNECT_TCP( '192.168.205.143', '1290' )
fails. Our internal firewall quite rightly doesn't allow a connection from "any port" on the database server to "any port" on my PC.
Is there any workaround for this issue, short of trying to get my security officer to open up so that "any port" on the database server can connect to "any port" on my windows client? I can change "debug preferences" in sqldeveloper to point to only one port on my windows client, but since I cannot control what port on the server the DBMS_DEBUG_JDWP.CONNECT_TCP procedure chooses when it tries to connect to my client, that is only a halfway solution as I see it.

Wrong install Disc, that one is machine specific, & doubtful a reinstall will help all that much.
More RAM will likely help, but not awfully likely it'll be 50%.
To tell, ehen it gets slow, Open Activity Monitor, Show:>All Processes, sort on CPU%, see if anything using too much CPU% when this happens, click on Memory tab, do you have many Pageouts?
