Yes, I run the ppp manually. I did run iptable manually, but did not
seems anything added to the list?

~$ sudo /sbin/iptables -t nat -A POSTROUTING -o ppp0 -j MASQUERADE

~$ sudo /sbin/iptables -L
Chain INPUT (policy ACCEPT)
target     prot opt source               destination

Chain FORWARD (policy ACCEPT)
target     prot opt source               destination

Chain OUTPUT (policy ACCEPT)
target     prot opt source               destination

Yes,  I added net.ipv4.conf.default.forwarding=1 in /etc/sysctl.conf

I also tried ifconfig eth1 down and run eth1 by udhcpc, but failed.

$ sudo /sbin/udhcpc -i eth1
udhcpc (v0.9.9-pre) started

Sending discover...
Lease failed:

~$ cat /etc/resolv.conf
nameserver 203.49.70.20
nameserver 139.134.2.190

Did that mean? Why ISP dhcp server did not respose? If that does not
work on my laptop, the wifi router won't get it work either?

Thank you.
