Hello folks,

Is there a way to do some packet mangling on NetBSD for the incoming and 
outgoing packet, something similar to the cisco's route-maps ? Here is my 
problem: I want all packets going from my IP address on TCP port 2000 to have 
TTL=12,  TOS=2 and precedence=3. Also I want all the packets that come to 
NetBSD router from src. address_A to dest. address_B to have TOS=3.

TIA,
M
