We are using Ipchains. I guess that makes no difference. At the moment we do the
following:

For Example (all rules for the same device):
1. filter ACKs by using u32
2. filter a specific IP by using ipchains -m (because we masquarade) with its
own tc fw
3. filter ToS by using u32
4. filter by another IP with ipchains -m with its own tc fw

With only one tc fw per device (and using 8bit values with ipchains -m to
specifie the targetclass) i guess the order like shown above could not be
maintained. It would look like

2. 4. 1. 3. or 1. 2. 4. 3. depending on the positon of the tc fw filter. The
same order like in the example can not be achieved. Am I right with that
assumption?

Is it possible to have more than one of these "global" tc fw filters for one
device?


Greetings Nils
