Hi,
I think you will find that this is broadcast traffic on the green lan.  The 
firewall rule that will be causing this to be dropped will be in the system 
access rules.  I wouldn't worry about it if i were you.  Also, setting the 
allow green to green - forward any only has any effect if you have more than 
one green interface in your system.

Subject: [Efw-user] Inter-Zone Firewall Blocking Traffic on Green (Port 137/138)

 

I'm using the default inter-zone traffic settings for the firewall, which shows 
it allows GREEN -> GREEN ANY.  However, I am logging blocked packets on the 
firewall, and I see this:
 
 INPUTFW:DROP UDP (br0) 192.168.1.199:137 -> 192.168.1.255:137
 
 It seems it is still blocking inter-zone traffic - the GREEN interface is 
configured on the 192.168.1.0/24 subnet.
 
 Anyone have any ideas how to stop this?  It even happens if I turn off the 
inter-zone firewall altogether.  The only thing that looks different in the 
logs to me is that blocked traffic from the uplink state INPUT:DROP, whereas 
these inter-zone logs say INPUTFW:DROP.
 
 I tried adding IP addresses specifically to the inter-zone firewall as well, 
setting it to allow FROM 192.168.7.199 to 192.168.7.255 on TCP+UDP ports 
137/138, and it still shows that it drops them.
 
 I've tried turning off services such as IPS as well, without any luck.  Does 
anyone have any idea at all?  If you look at your logs, do you see these 
dropped packets as well?  Just running a simple 'net view /domain' on a windows 
box on green will force it to make the attempt, and for me it generates the 
dropped packets in the live firewall log every time.
 
 The way the hardware is configured is eth0 (which automatically runs as br0) 
is green, and eth1 is red, if it makes a difference.
