Now, suppose that you have some applications, like FTP server,
Webserver, Email server...
.... on ONE server, which is placed on DMZ host

The server has only ONE Ethernet card.

I would like to prioritize the traffic.
An application APP1, can set a TOS on frames sent.

How can (with IPTABLES.. I suppose) make sure that ALL the traffic for
APP1, will be prioritized ?!

- ALl the examples I have seen, are only with 2 Ethernet cards....
- My app1 application, can add a TOS of 184 (0xb4) and I can see only
IPTABLES managing TOS with values < (somehting like 10....) But at
least, doesn't accept such high value !?!?!
