Unfortunately, rtadvd(8) shipped with FreeBSD 4.9-RELEASE and 5-CURRENT are very similar to KAME's. :) It seems that KAME folks separates static configuration from dynamic configuration. ab> /me looks in the general direction of Umemoto-san ^^ ^^; 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/
