When I manually assign IPv6 address, jp> connection works. My system is 4.8-RELEASE, PPP Version 3.1 - Apr 3 2003. You cannot assign IPv6 address to tun0 by receiving RA on 4.8-RELEASE. It is because, ppp(8) assigns link-local address with prefixlen is /128. But, RA expects that link-local is /64. jp> axxem.hide:~# ifconfig tun0 jp> tun0: flags=8051<UP,POINTOPOINT,RUNNING,MULTICAST> mtu 1500 jp> inet6 fe80::290:27ff:fe78:9275%tun0 --> fe80::2d0:baff:fef4:e80%tun0 prefixlen 128 scopeid 0x6 jp> inet 1.2.3.4 --> 5.6.7.8 netmask 0xffffffff jp> Opened by PID 42838 This problem was fixed at 2003/04/29. You can use it by upgrading your box to recent 4-STABLE. If you don't want upgrading your box, apply the following patchs to src/usr.sbin/ppp and rebuilting ppp: http://www.imasy.or.jp/~ume/FreeBSD/ppp-patches-4.8-release.tar.gz Sincerely, -- Hajimu UMEMOTO @ Internet Mutual Aid Society Yokohama, Japan ume@mahoroba.org ume@bisd.hitachi.co.jp ume@{,jp.}FreeBSD.org http://www.imasy.org/~ume/
