Problem connecting via Firewall utilizing CMAN

Hi all

SERVER 1 (LAN)
- Windows 2003 Server

• Oracle 9.2.0.6
• CMAN 9.2.0.1 (on port 1610)

SERVER 2 (LAN)
- Windows 2000 Server

• Client Oracle 9.2.0.1

SERVER 3 (DMZ)
- Windows 2000 Server

• Client Oracle 9.2.0.1

CONNECTION 2 to 1 : everytime OK

CONNECTION 3 to 1 via Firewall (port 1610 and 1521 open) : sometimes OK, sometimes NOT

Why when I connect from 3 to 1 sometimes works and sometimes (after reboot) doesn't work?

When it doesn't work:
- TNSPING work

• TELNET on 1610 work
• Entry in listener.ora : 28-SEP-2005 14:24:55 * (CONNECT_DATA= (SERVER=DEDICATED)(SID=TSIPACK)(CID=(PROGRAM=D:\oracle\ora92\bin\sqlplus.exe) (HOST=XLIPACK)(USER=ebs4))) * (ADDRESS=(PROTOCOL=tcp)(HOST=10.0.0.254) (PORT=7399)) * establish * TSIPACK * 0

cman.ora
CMAN =
  (ADDRESS = (PROTOCOL = TCP)(HOST = 10.3.0.3)(PORT = 1610)) CMAN_PROFILE = (PARAMETER_LIST=

		(MAXIMUM_RELAYS=128)
		(LOG_LEVEL=2)
		(TRACING=no)
		(RELAY_STATISTICS=no)
		(REMOTE_ADMIN=no)
		(SHOW_TNS_INFO=no)
		(USE_ASYNC_CALL=yes)
		
		)

Thanks
