arps (or any broadcast traffic for that matter)  received on an interface 
out the others.   You would have to use proxy arping on the firewall or 
similar if you required this to happen.   The better way to go about it I 
suspect is to use a WINS service.
   May be. What is proxy arp'ing?
   But that does not really answer my question which, upon reflection, may 
not have been clear.
   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?
