[LARTC] Using multiple uplinks

[Michel Angelo da Silva Pereira]

	Hi, I'm with a problem here on configuring our server to use multiple 
uplinks with different providers.
	The packet goes though on my way, but there is some lost packets that I 
don't known where it's going and causing my link to goes slow and stop 
sending/receiving data.
	Here i'm listing the route tables and the rules. It's only for 1 IP.

[root@firewall /root]# ip ro li
200.148.140.252/30 dev eth4  proto kernel  scope link  src 200.148.140.253
172.16.2.0/24 dev eth2  proto kernel  scope link  src 172.16.2.254
default via 200.148.140.254 dev eth4

[root@firewall /root]# ip ro li table 4
200.153.199.64/26 dev eth3  proto kernel  scope link  src 200.153.199.116
172.16.2.0/24 dev eth2  proto kernel  scope link  src 172.16.2.254
default via 200.153.199.65 dev eth3

[root@firewall /root]# ip rule list
0:      from all lookup local
32764:  from all fwmark        4 lookup speedy
32765:  from all lookup main
32767:  from all lookup 253

[root@firewall /root]# iptables -t mangle -L -nv
Chain PREROUTING (policy ACCEPT 11M packets, 3773M bytes)

	Thanks for the help
