当然freebsd必须是router接入ipv6
而且这样的话会开放很多本地的http和telnet

freebsd下
#!/bin/sh
sysctl net.inet6.ip6.accept_rtadv=0
sysctl net.inet6.ip6.forwarding=1
sysctl net.inet6.ip6.keepfaith=1
ifconfig create faith
ifconfig faith0 up
route add -inet6 xxxx:yyyy:zzzz:wwww:vvvv:uuuu:aabb:ccdd -prefixlen 128 ::1
route change -inet6  xxxx:yyyy:zzzz:wwww:vvvv:uuuu:aabb:ccdd -prefixlen 128 -ifpfaith0  //这个接在上面那行的，bbs线是有问题
/usr/sbin/faithd http
/usr/sbin/faithd telnet

xxxx:yyyy:zzzz:wwww:vvvv:uuuu:aabb:ccdd
中xxxx:yyyy:zzzz:wwww:vvvv:uuuu，为ipv6的前缀
aabb:ccdd 为你本地ipv4的16进制码
