IP Firewall with Quality of Service

[Stefan Saliba]

Does anyone know if ipchains supports Quality of service by IP or does anyone know of a firewall software with Quality of Service running under Linux ?

[Doug Preston]

reading the RFC2212 - Quality of Service specs

I would say that since a firewall is intended to block traffic that it probably fails in that articles intent. But using it to protect your system from attacks or unwanted connections works great without causing a breakdown in communication with those allowed to connect. If you have machines on the local network that ipchains has port forwarding for the connection will not notice any degredation in service. Nor will any machine on your local network passing to the internet through the firewall machine.

IPChains allow changes of Quality of service. Check the ipchaings man page for information on the -t option.

This is covered in the IP-Chains Howto http://www.linuxdoc.org/HOWTO/IPCHAINS-HOWTO-4.html under the topic "Manipulating the Type Of Service".
