LARTC - Jan 2006 - Problems with load balancing

I have 2 providers, each on a separate interface, and a LAN on the third
interface. After I do the load balancing, only one line is used and the
traffic gets through very hard. Also, a simple command, like iptables -t nat
-L, takes very long to show the output. Does anyone know what could be
wrong?
I list my outputs here:

taurus:~# ip route show all
192.168.2.0/26 dev eth0  proto kernel  scope link  src 192.168.2.22
86.55.39.128/25 dev eth1  proto kernel  scope link  src 86.55.39.223
10.0.0.0/24 dev eth2  proto kernel  scope link  src 10.0.0.1

Hi!

I would guess it''s a problem with your DNS relsolution. Try
"route" and
"route -n" and
check if there''s a difference. "route -n" disables the DNS
resolution.

Hi!

Try to change your DNS-Server. Edit the file /etc/resolv.conf, remove
all "nameserver" lines and add one new nameserver. Try something like
nameserver 192.58.128.30
Ask your provider for a DNS-Address and take this one.
After saving the file, "route" should execute fast immediatly.
Read "man resolv.conf"!
