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 > the ip forwarding is still enabled right ? 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... Sending discover... 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. Jim -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe". Trouble?
