我今天在cisco路由器上设置了pptp服务器。 远程客户端IP地址通过DHCP在此Cisco路由器上分配。 此外，我设置了选项249和121为我的VPN客户端提供无类路由。
选项249和121用于两个路由：10.0.0.0/8和192.168.0.0/16。
我在Windows XP和Mac OS X Snow Leopard上testing了这个configuration。 所有的工作都很好。
但是我的Windows 7电脑只能从选项121获得第一个地址，而忽略下一个。 为什么？
我如何修复它或跟踪/debugging它？
dhcp池的configuration是：
ip dhcp pool pptp-users network 10.255.241.0 255.255.255.0 default-router 10.255.241.1 dns-server 10.255.249.40 netbios-name-server 10.255.249.40 option 249 hex 080a.0aff.f101.10c0.a80a.fff1.01 option 121 hex 080a.0aff.f101.10c0.a80a.fff1.01 如果我在选项中改变路线，所有的工作方式都是一样的。 Windows XP和MacOS X的作品。 Windows 7刚刚获得第二个路由10.0.0.0/8
