Hello m0n0-list

I would like to make SLP available across several m0n0-interfaces.

Example configuration:
WAN: whatever..
LAN: 192.168.0.0/24
OPT1: 192.168.1.0/24
OPT2: 192.168.2.0/24

There are a total of 4 OPTs but to make it short, an example rule(set) should 
suffice. 

What I want: SLP passes from LAN to OPT1 and OPT2, vice versa, BUT SLP does 
not pass from OPT1 to OPT2 (vice versa).

I've figured that when Konqueror tries to look up SLP Services there these two 
logs found: (Destinations only)
224.0.0.251,     port 5353 UDP
239.255.255.253, port 427  UDP
224.0.1.35,      port 427  UDP
224.0.1.22,      port 427  UDP

But I do not know how to create the rules in order to achieve the goal, I've 
mentioned above.

Bridging is not the solution I'd prefer, I rather have some rules to achieve 
my goal.
