hello, regarding to the note on: http://www.FreeBSD.org/cgi/getmsg.cgi?fetch=0+2538+/usr/local/www/db/text/2001/freebsd-net/20010506.freebsd-net the symptom is repeatable. however, it seems to me that the multi destination mode is poorly documented, and needs certain (strange) configuration to work properly. i have no idea how can it be useful. the destination tunnel gateway address is taken from rt_gateway, so i guess you'd need to set routing table like this: % route add -inet 192.168.10.0 24.27.51.59 % route change -inet 192.168.10.0 24.27.51.59 -ifp gif0 which seems very counter-intuitive to me (NOTE: i did not test this). my preference is to dropp support for multi-destination mode from gif(4), as the multi-destination behavior is violating network layering (rt_gateway is in inner header, and gif(4) multi-destination mode uses it to determinte outer header). itojun To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-net" in the body of the message
