The dhclient configuration is default. The system boots up fine. The system is running 5.4-RELEASE. Problem: dhclient will not restart while I have my ipv6 aliases bound to vr0 (may restart once shortly after boot but no more which seems very wierd). paste from log; dhclient: vr0: not found Workaround: I wrote a script to unbind my IPV6 vhosts from vr0 inorder to restart dhclient, and then rebind them. While the vhosts are unbound, dhclient will never fail. >How-To-Repeat: Enable an IPV6 tunnel on a home DHCP connection via the following settings: ipv6_enable="YES" ipv6_network_interfaces="gif0 vr0" ipv6_ifconfig_gif0="2001:618:400::1899:36af prefixlen 128" ipv6_defaultrouter="fe80::%gif0" ipv6_gateway_enable="YES" rtadvd_enable="YES" rtadvd_interfaces="vr0" gif_interfaces="gif0" gifconfig_gif0="24.153.xx.xxx 213.121.xx.xx" (IPS filtered) <snipped> Than we bind our IPV6 aliases (230 of them) to vr0. Restarting dhclient will fail with "dhclient: vr0: not found". >Fix: >Release-Note: >Audit-Trail: >Unformatted:
