samba - Mar 2002 - Problem with TSM-Client and firewall

Hi,

we use a checkpoint with a dmz and a w2k client. we open follow ports 
between tsm-server and client 1500,1501, 1580 and 1581. after q 
filespace i get no answer from the tsm-server (log checkpoint). i use 
schedmode polling and with netstat -an on tsm-server i see my client 
with status syn_rcvd.

thanks

markus
