用pppd拨号成功，也能上网，可以ping通
www.sina.com.cn比如这次拨号结果为：
local IP address
10.3.82.80
remote IP address 10.64.64.64
primary DNS address 211.136.20.203
secondary DNS address 211.136.20.203
Script /etc/ppp/ip-up started (pid 618)
Script /etc/ppp/ip-up finished (pid 618), status = 0xff
# ifconfig ppp0结果为
ppp0 Link encap:Point-to-Point Protocol
inet addr:
10.3.82.80 P-t-P:10.64.64.64 Mask:255.255.255.255

想在公网访问这个开发板的webserver，可是拨号所得的ip:10.3.82.80分明就是局域网ip，我应该访问哪个ip呢，希望知道的指点下，谢谢
