change your default gateway
After the dial succeed, the default gateway may still be the gateway of private network, and the public address can not be accessed from internet. So in this case the default gateway must be changed to the public one, to ensure the server can be accessed innernet and internet. Get current route table by:
1

| Kernel IP routing table
Destination Gateway Genmask Flags Metric Ref Use Iface
0.0.0.0 192.168.1.1 0.0.0.0 UG 101 0 0 eth1
123.120.0.1 0.0.0.0 255.255.255.255 UH 0 0 0 ppp0
