I have a Linux firewall with ipchains.
The connection is a bit to slow so I like to reserve some bandwith for mail and www that goes to DMZ.
(What I realy want to do is to give trafic to my mail and www server higest priority. As it is now it is awful slow to visit the www-server and to read mail from outside if someone on the Private Net is downloading a lot from internet.
I don't like to switch to 2.4 kernel because it seems like I cannot set the Masquerading Timeout like I can do with ipchains.
(ipchains -M -S 72000 10 60)
Can someone help me out how to implement this?
