As TOS value will only be used within the box, I would prefer use fwmark as QoS key. I won't alter IP header this way and result will be exactly the same. I use TOS mangling when I need my routing/QoS "key" to get exported over the network so it can be used by others systems. For Kenneth : if you still want to use TOS, I would reset it to 0 in POSTROUTING chain, as some silly guys drop packets with non null TOS value. -- http://www.netexit.com/~sid/ PGP KeyID: 157E98EE FingerPrint: FA62226DA9E72FA8AECAA240008B480E157E98EE >> Hi!
