Message-ID: <3e660b98.769a.0@unacs.bg> (raw)




Hi,  
 
looks like some of correct packes are droped  
 
Chain FORWARD (policy ACCEPT 0 packets, 0 bytes) 
num   pkts bytes target     prot opt in     out     source               destination

1    36142   16M ACCEPT     all  --  *      *       0.0.0.0/0            0.0.0.0/0
         TOS 
match 0x00 
2     168K   54M ACCEPT     all  --  *      *       0.0.0.0/0            0.0.0.0/0
         TOS 
match 0x10 
3       27  1782 LOG        all  --  *      *       0.0.0.0/0            0.0.0.0/0
         LOG 
flags 0 level 4 
4       27  1782 DROP       all  --  *      *       0.0.0.0/0            0.0.0.0/0

 
 
in log we can see that TOS of packets is 0x0 they are also packets with 0x10
