   I am setting up a suse linux v9.1 host to provide file and print 
services to a mix of os/2 and windows clients. In this case windows is not 
a problem. I am running into difficulty getting the os/2 clients to see 
the resources on the linux server.
   The main problem is the firewall. Without the firewall os/2 hosts have 
no problem with accessing resources. With the firewall the hosts cannot 
access the server.
   There seems to be some problem related to ARP. The os/2 hosts broadcast 
a request to a nameserver (x.x.x.255) looking for the resource. Without 
the firewall there is an exchange of arp data; with the firewall, the 
packets are blocked.
   What port is the firewall blocking? In the Suse firewall config file 
there is:
FW_SERVICES_EXT_TCP="139 445 760 http https imap imaps nfs smtp ssh"
FW_SERVICES_EXT_UDP="137 138 760 788:799 nfs 111"
   Yet when I attempt to access the linux server, I find this in the 
messages log:

Oct 31 16:52:34 sma-server2 kernel: SFW2-DROP-BCASTe IN=eth1 OUT= 
MAC=ff:ff:ff:ff:ff:ff:00:03:ff:29:24:34:08:00 SRC= 
DST= LEN=78 TOS=0x00 PREC=0x00 TTL=64 ID=140 PROTO=UDP 
SPT=137 DPT=137 LEN=58

   00:03:ff:29:24:34/ is the MAC/IP of the host requesting 
info. The firewall dropped the broadcast packet even though the firewall 
is configured to allow it. Am I reading the logs correctly?
