[LARTC] High Availability and QoS (problem with IP aliasing)

[LARTC] High Availability and QoS (problem with IP aliasing)

[Javier Miguel Rodriguez]

	Hello

	I am using Ultramonkey to create a highly available firewall linux
cluster. Everything works okay with ipchains or iptables...

	The problem is with QoS... Ultramonkey creates a "cluster virtual" IP 
address called eth0:0. I am using cbq script to control the bandwith, but it 
does NOT work with ip-aliasing

	Does anybody how to do QoS with an ip-aliased interface?
	
	Thank you in advance

	Greetings from Spain!

Just use the "original" interface, meaning: use eth0 instead of eth0:0.
The same is true for iptables rules. I'm also setting up a HA firewall
with iptables and traffic shaping; actually one half is running right
now (the other half has yet to be set up).
