OpenWrt 中配置了 VPN ，但无法启用，求解

安装 12.09 版的 OpenWrt ，现在通过 pppoe 拨号，可用；

想内置 VPN ，安装了 ppp-mod-pptp ，/etc/config/network 配置如下，但 VPN 还是无法启用。

不知道是什么问题，附图是 LuCI 中的一个截图，不知道能不能帮着理解问题，也发出来。

/etc/config/network 配置：

config interface 'loopback'
option ifname 'lo'
option proto 'static'
option ipaddr '127.0.0.1'
option netmask '255.0.0.0'

config globals 'globals'
option ula_prefix 'fd0e:57bc:746f::/48'

config interface 'lan'
option ifname 'eth0.1'
option type 'bridge'
option proto 'static'
option ipaddr '192.168.1.1'
option netmask '255.255.255.0'
option ip6assign '60'

config interface 'wan'
option ifname 'eth0.2'
option proto 'pppoe'
option username 'llll384'
option password 'llll82'
option peerdns '1'
option defaultrout '1'

config interface 'wan6'
option ifname '@wan'
option proto 'dhcpv6'

config switch
option name 'switch0'
option reset '1'
option enable_vlan '1'

config interface 'wifi'
option proto 'static'
option ipaddr '192.168.10.190'
option netmask '255.255.255.0'
option gateway '192.168.10.1'
option dns '8.8.8.8'

config switch_vlan
option device 'switch0'
option vlan '1'
option ports '0t 2 3 4 5'

config switch_vlan
option device 'switch0'
option vlan '2'
option ports '0t 1'

config interface 'vpn'
option proto 'pptp'
option server 'jp.nnnnnn.net'
option username 'vpnnnnn'
option password 'pfnnnnn7'
option buffering '1'
option pppd_options 'mppe required'

关闭 Linux ，重启路由器还是不行。 :(

看一眼 openwrt 的 system log 吧，如果 vpn 是你自己搭的，也看看那边的 log

@ericFork 不好意思，这两个 log 我找了一下没有找到，是在什么位置？
