Yes, what you are trying to do is allowed and is supported. In fact several= bugs=20 were fixed to support such configuration properly. For example, see these c= ommits: http://svnweb.freebsd.org/base?view=3Drevision&revision=3D225947 http://svnweb.freebsd.org/base?view=3Drevision&revision=3D225223 I vague remember fixing a bug with this exact description but I am having a bit difficult locating the patch. Could you please indicate what version you are running ? --Qing > -----Original Message----- > From: owner-freebsd-net@freebsd.org [mailto:owner-freebsd- > net@freebsd.org] On Behalf Of M.
