After about 20 days hard work, it's been tested today.
the peak speed at 225k bytes/s  :)
but TCO not cheap......  Beside all ,it's worked for me..
paste shell script here:

 ---------- Compile kernel first -----------------

 #with below options

 [*] Socket Filtering
<*> Unix domain sockets
[*] TCP/IP networking
[*] IP: multicasting
[*]   IP: advanced router
[*]     IP: policy routing
[*]       IP: use netfilter MARK value as routing key
[*]       IP: fast network address translation
[*]     IP: equal cost multipath 
[*]     IP: use TOS value as routing key
[*]     IP: verbose route monitoring
[*]     IP: large routing tables

 --------------------- Shell script BEGIN --------------------

 echo 1 > /proc/sys/net/ipv4/ip_forward 

 dhclient eth0
dhclient eth1
# get ip address from ISP's CM-DHCPD

 ifconfig eth2 172.19.0.1 netmask 255.255.0.0

 ext_ip0=`ifconfig eth0 | grep inet | cut -f 2 -d : | cut -f 1 -d \ `
ext_ip1=`ifconfig eth1 | grep inet | cut -f 2 -d : | cut -f 1 -d \ `

 insmod /lib/modules/2.4.20-xfs/kernel/net/sched/sch_teql.o

 iptables -t nat -A POSTROUTING   -o eth0  -j SNAT --to-source $ext_ip0
iptables -t nat -A POSTROUTING   -o eth1  -j SNAT --to-source $ext_ip1

 dhcpd eth2
# set default route in dhcpd.conf as 172.19.0.1

 gw0=`ip route list | grep eth0 | grep default | cut -f 3 -d \ `
gw1=`ip route list | grep eth1 | grep default | cut -f 3 -d \ `

 route delete default gw $gw0
route delete default gw $gw1

 ip route replace default nexthop via $gw0 dev eth0 weight 1 nexthop via $gw1 dev eth1 weight 1

 ip route flush cache 

This spring festival, I spend all the holiday on DOC & Linux-ip-chunk project.

 
 
                       -------------
                      |        eth0 | <-----> cable modem
Private Network  <--> | eth2        | (get ip from isp)
 (172.19.0.0)SNAT     | .0.1   eth1 | <-----> cable modem
                       ------------- (get ip from isp)
                        Linux router

It's seemed a complex & puzzleheaded project.
I want to made Private Network bound transfer speed with all that egress connection
